Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company	Basis of Presentation These unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") have been condensed or omitted in these interim statements. Accordingly, these condensed consolidated financial statements are to be read in conjunction with the financial statements and notes included in the Company's Annual Report on Form 10-K for its fiscal year ended April 2, 2016 . These interim statements include all adjustments (consisting of only normal recurring adjustments and accruals) necessary for a fair presentation of results for the interim periods presented. The results for interim periods are not necessarily indicative of the results of operations for the entire year. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates. Management believes that the estimates used are reasonable. Significant estimates made by management include: revenue recognition; inventory valuation; product warranty reserves; allowance for doubtful accounts; accrued restructuring costs; share-based compensation; income taxes including the valuation of deferred tax assets; fair value measurements; valuation of long-lived assets; valuation of goodwill; and valuation of acquired technology. There have been no significant changes to the Company's significant accounting policies from those presented in Note 2 “Summary of Significant Accounting Policies” to the consolidated financial statements included in the Company's Annual Report on Form 10-K for its fiscal year ended April 2, 2016 . All references to years or quarters relate to fiscal years or fiscal quarters unless otherwise noted. The fiscal quarters ended July 2, 2016 , April 2, 2016 , and June 27, 2015 consisted of 13-week periods.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date for implementation of ASU 2014-09 by one year and are now effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted but not earlier than the original effective date. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (ASU 2016-08), which clarifies the implementation guidance of principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing (ASU 2016-10), which clarifies the identification of performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients (ASU 2016-12), to improve guidance on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The effective date and transition requirements in ASU 2016-08, ASU 2016-10, and ASU 2016-12 are the same as the effective date and transition requirements of ASU 2015-14. We have not yet selected a transition method and we are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. The new standard is effective for the Company's fiscal year ending March 30, 2019. In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation – Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, which would be the Company's fiscal year ending March 31, 2018. We do not expect the adoption of ASU 2016-09 to have a material effect on our financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, “Leases.” ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosing key information about leasing arrangements. ASU 2016-02 is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, which would be the Company's fiscal year ending March 29, 2020.We do not expect the adoption of ASU 2016-02 to have a material effect on our financial position, results of operations or cash flows.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial Assets and Liabilities Measured at Fair Value ASC Topic 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include the following: • Level 1 , defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; • Level 2 , defined as inputs that are observable either directly or indirectly such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and other inputs that can be corroborated by observable market data; and • Level 3 , defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of July 2, 2016 and April 2, 2016 was as follows (in thousands): July 2, 2016 Level 1 Level 2 Level 3 Total Cash equivalents: Money market securities $ 3,081 $ — $ — $ 3,081 Commercial paper — 16,891 — 16,891 Total cash equivalents $ 3,081 $ 16,891 $ — $ 19,972 Short term investments - available for sale: U.S. treasury fund $ 1,007 $ — $ — $ 1,007 Commercial paper $ — $ 1,546 $ — $ 1,546 Government agencies $ — $ 1,953 $ — $ 1,953 Total short-term investments - available for sale $ 1,007 $ 3,499 $ — $ 4,506 Forward purchase or (sale) contracts: Japanese Yen $ — $ (122 ) $ — $ (122 ) New Taiwan Dollar — (5 ) — (5 ) Korean Won — (6 ) — (6 ) Euro — 189 — 189 British Pound — (100 ) — (100 ) Chinese Renminbi — (34 ) — (34 ) Singapore Dollar — (1 ) — (1 ) Total forward contracts $ — $ (79 ) $ — $ (79 ) Deferred compensation plan assets:* Mutual funds and exchange traded funds $ 2,060 $ — $ — $ 2,060 Money market securities 730 — — 730 Total deferred compensation plan assets $ 2,790 $ — $ — $ 2,790 April 2, 2016 Level 1 Level 2 Level 3 Total Cash equivalents: Money market securities $ 4,643 $ — $ — $ 4,643 Commercial paper — 12,140 — 12,140 Total cash equivalents $ 4,643 $ 12,140 $ — $ 16,783 Short term investments - available for sale: U.S. treasury fund $ 1,003 $ — $ — $ 1,003 Commercial paper $ — $ 997 $ — $ 997 Government agencies — 13,252 — 13,252 Total short-term investments - available for sale $ 1,003 $ 14,249 $ — $ 15,252 Forward purchase or (sale) contracts: Japanese Yen $ — $ (31 ) $ — $ (31 ) New Taiwan Dollar — 5 — 5 Korean Won — 129 — 129 Euro — (367 ) — (367 ) Chinese Renminbi — (1 ) — (1 ) Singapore Dollar — 20 — 20 Total forward contracts $ — $ (245 ) $ — $ (245 ) Deferred compensation plan assets:* Mutual funds and exchange traded funds $ 1,916 $ — $ — $ 1,916 Money market securities 588 — — 588 Total deferred compensation plan assets $ 2,504 $ — $ — $ 2,504 *These investments represent assets held in trust for the deferred compensation plan For Level 1 assets, the Company utilized quoted prices in active markets for identical assets. For Level 2 assets, exclusive of forward contracts, the Company utilized quoted prices in active markets for similar assets. For forward contracts, spot prices at July 2, 2016 and April 2, 2016 were utilized to calculate fair values. During the first quarter of 2017 and 2016 , there were no transfers between Level 1, 2 or 3 assets. Investments The Company’s investments at July 2, 2016 and April 2, 2016 were as follows (in thousands): Unrealized July 2, 2016 Cost Gain Loss Fair Value Available-for-sale securities (current): Government agencies 1,951 2 — 1,953 Commercial paper 18,437 — — 18,437 Total investments (current) $ 20,388 $ 2 $ — $ 20,390 Available-for-sale securities (non-current): Mutual funds, exchange traded funds and money market securities* 2,740 50 — 2,790 Total investments (non-current) $ 2,740 $ 50 $ — $ 2,790 Unrealized April 2, 2016 Cost Gain Loss Fair Value Available-for-sale securities (current): Commercial paper $ 13,137 $ — $ — $ 13,137 Government agencies 13,247 5 — 13,252 Total investments (current) $ 26,384 $ 5 $ — $ 26,389 Available-for-sale securities (non-current): Mutual funds, exchange traded funds and money market securities* $ 2,507 $ — $ (3 ) $ 2,504 Total investments (non-current) $ 2,507 $ — $ (3 ) $ 2,504 *These investments represent assets held in trust for the deferred compensation plan For purposes of determining gross realized gains and losses and reclassification out of accumulated other comprehensive income (loss), the cost of securities sold is based on specific identification. Net unrealized holding gains and losses on current available-for-sale securities included in accumulated other comprehensive income (loss) were insignificant as of July 2, 2016 and April 2, 2016 .

Share-Based Compensation

Share-Based Compensation	3 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation The Company's share-based compensation consists of stock-settled stock appreciation rights (SARs), time-based restricted stock unit awards (time-based RSUs), performance-based restricted stock unit awards (performance-based RSUs), and an employee stock purchase plan. The performance-based RSUs specify certain performance or market-based conditions that must be achieved in order for the awards to vest. The Company recognizes expense related to the fair value of SARs and employee stock purchase plan using the Black-Scholes model to estimate the fair value of awards on the date of grant. SARs grant the right to receive shares of the Company's stock equivalent to the increase in stock value of a specified number of shares over a specified period of time, divided by the stock price at the time of exercise. The fair value of time-based RSUs and performance-based RSUs contingent on performance criteria are measured on the grant date based on the market value of our common stock. The performance-based RSUs contingent on market conditions must achieve the total shareholder return (TSR) measures in order for the awards to vest, and the fair value of the awards is calculated on the grant date using a Monte Carlo simulation model. The Company recognizes compensation expense for all share-based compensation awards, net of estimated forfeitures, on a straight-line basis over the requisite service period of the award. The compensation cost on performance-based RSUs contingent on TSR measure is recognized over the related service period, even if the market condition is never satisfied. The Company granted a total of 495,500 time-based RSUs and 195,000 performance-based RSUs contingent on a TSR measure during the first quarter of 2017 , but did not grant any SARs. Share-based compensation expense was included in the Company’s Condensed Consolidated Statements of Operations as follows: Fiscal quarter ended (In thousands) July 2, 2016 June 27, 2015 Cost of sales $ 120 $ 129 Selling, general and administrative 977 715 Research, development and engineering 194 219 Total share-based compensation expense $ 1,291 $ 1,063 The Company does not capitalize share-based compensation costs. As of July 2, 2016 , the Company had $9.9 million of total unrecognized share-based compensation costs, net of estimated forfeitures, which are expected to be recognized over a weighted average period of 2.0 years.

Business Acquisitions

Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions Fiscal 2015 On January 15, 2015, the Company acquired all of the outstanding shares of Wuhan Topwin Optoelectronics Technology Co., Ltd. (Topwin), a Chinese manufacturer of laser-based systems for $7.6 million in cash and 748,944 shares of ESI common stock issuable over a three year period, valued at approximately $2.9 million as of the acquisition date. Out of the $2.9 million in equity, one-half, or 374,472 shares, is contingent-based consideration and one-half, or 374,472 shares, is non-contingent and will be issued over a three year period beginning June 30, 2015. The contingent consideration is based on future performance of Topwin, as evaluated against targets for net income for each year over a three year period. One-third of the contingent shares will be issued after each year if the target is met for that year. However, failing to meet stated targets will result in none of the contingent shares being issued for that year. As of the acquisition date, the fair value of 374,472 shares of contingent consideration was estimated to be $0.4 million and the fair value of 374,472 shares of non-contingent consideration was estimated to be $2.5 million . The fair value of the non-contingent and contingent shares to be issued over the three year period was determined based on the estimated share price as of the issuance date derived through Monte Carlo simulation, discounted back to the acquisition date. The value of the contingent shares included an estimate of the probability of attainment of the net income targets. Analysis supporting the purchase price allocation included a valuation of assets and liabilities as of the closing date, an analysis of intangible assets and a detailed review of the opening balance sheet to determine other significant adjustments required to recognize assets and liabilities at fair value. Through the first quarter of 2017 , zero and 212,217 shares of ESI common stock have been issued in connection with contingent and non-contingent consideration under the purchase agreement, respectively. Additionally, the Company agreed to issue, on the same terms described above, up to approximately 513,328 shares valued at $2.0 million , which, together with cash amounts of $0.2 million , is treated as compensation to an employee in the Company who was also a former shareholder of Topwin. The compensation expense will be recognized over a three year period. Through the first quarter of fiscal 2017 , the Company has recognized $1.2 million in compensation expense related to this agreement. This expense was comprised of $1.1 million of share-based compensation and $0.1 million of amortization. Through the first quarter of fiscal 2017 , zero and 145,427 shares of ESI common stock have been issued in connection with contingent and non-contingent components of compensation expense, respectively. The total purchase price of approximately $10.5 million , net of cash acquired, was allocated to the underlying assets acquired and liabilities assumed based on their fair values, as shown in the following table: (In thousands) Accounts receivable, net of allowances of $268 $ 454 Inventory 544 Prepaid expense and other current assets 295 Property, plant and equipment 23 Acquired intangibles 3,618 Goodwill 7,445 Accounts payable and other accrued liabilities (1,859 ) Total purchase price, net of cash acquired $ 10,520 The acquisition is expected to enable the Company to gain entry into the low total-cost-of-ownership solutions market in China and the goodwill of approximately $7.4 million recognized as a result of the acquisition was assigned to the Topwin reporting unit. The premium paid over the fair value of the individual assets acquired and liabilities assumed reflects the Company’s view that this acquisition was the result of a competitive bid process and has provided the Company with innovative design and manufacturing capabilities for laser-based manufacturing solutions across a variety of complementary applications, together with direct access to local China market, supply chain and opto-electronics knowledge center. None of the goodwill is expected to be deductible for tax purposes. As a result of the acquisition, the Company recorded approximately $4.9 million of identifiable assets, including $3.6 million of identifiable intangible assets and $1.9 million of identifiable liabilities. The acquired intangible assets consisted primarily of $3.5 million of developed technology to be amortized over their useful lives, which range from one to ten years. In the first quarter of 2017 the Company did not incur any Topwin acquisition-related costs while it incurred approximately $154 thousand in the first quarter of 2016 ; these costs are included in Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations. The operating results of this acquisition are included in the Company’s results of operations since the date of acquisition. Pro forma financial information has not been provided for the acquisition of Topwin as it is not material to the Company’s operations and overall financial position. In the first quarter of 2017, the Company entered into an agreement with former Topwin shareholders to settle claims against withheld shares. Pursuant to the purchase agreement and the subsequent settlement agreement all shares withheld as escrow were released to the Company. As a result, the withheld shares initially treated as stock compensation were deemed to have forfeited in the current period and the shares representing contingent consideration and included as a component of purchase price were accounted for within equity and this subsequent settlement represents a non-cash investing and financing activity. Together these items represent the effective recovery of 63,114 shares, which at the date of recovery had a closing price of $6.30 per share. The purchase price of Topwin was not adjusted as the measurement period had elapsed.

Deferred Revenue Disclosure [Abstract]
Deferred Revenue	Deferred Revenue Generally, revenue is recognized upon fulfillment of acceptance criteria at the Company's factory and transfer of risk and title. Revenue is deferred whenever title transfer is pending, risk has not transferred, and/or acceptance criteria have not yet been fulfilled. Deferred revenue arises from, among other factors, sales to Japanese customers, shipments of substantially new products and shipments with custom specifications and acceptance criteria where the Company cannot demonstrate a track record of acceptance. For sales involving multiple element arrangements, the relative selling price of any undelivered elements, including installation services and similar items, is deferred until the elements are delivered and acceptance criteria are met. Revenue related to maintenance and service contracts is deferred and recognized ratably over the duration of the contracts. The following is a reconciliation of the changes in deferred revenue: Fiscal quarter ended (In thousands) July 2, 2016 June 27, 2015 Deferred revenue, beginning $ 7,685 $ 12,376 Revenue deferred 10,353 15,720 Revenue recognized (8,281 ) (13,135 ) Deferred revenue, ending $ 9,757 $ 14,961 Of the total of $9.8 million in deferred revenue at July 2, 2016 , $0.9 million is non-current and is included in Other liabilities on the Condensed Consolidated Balance Sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments & Contingencies The Company is party to a loan and security agreement ("Loan Agreement") with Silicon Valley Bank, which was amended on July 12, 2016. The amendments, among other things, included the modification of certain financial covenants, including the removal of Tangible Net Worth covenant for periods ending after March 31, 2016. Instead, the Company must now comply with two new financial covenants, including a quick ratio and an EBITDA loss threshold measured on a trailing twelve month basis. The Loan Agreement provides for a senior secured asset-based revolving credit facility (the “Credit Facility”) with up to $30 million available on a revolving basis, including a $15 million sublimit for letters of credit. The credit agreement expires March 20, 2018. At July 2, 2016 , the Company had no revolving loans or letters of credit outstanding under the Credit Facility, was in compliance with all covenants, and was not in default under the Loan Agreement. The commitment fee on the amount of unused credit was 0.3 percent. The Company mitigates credit risk by transacting with highly rated counterparties for foreign exchange contracts, letters of credit and other transactions where counterparty risk is a factor. The Company has evaluated the non-performance risks associated with the Company's lenders and other parties and believe them to be insignificant. From time to time the Company may be party to litigation arising in the normal course of business. Currently, the Company is not party to any litigation it believes would have a material adverse effect on the Company's financial position, results of operations or cash flows.

Segment and Geographic Information [Abstract]
Segment Reporting Disclosure [Text Block]	Segment and Geographic Information Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The chief operating decision maker ("CODM") is the Company's Chief Executive Officer. The Company operates in two segments, Component Processing and Micromachining. Included within Component Processing are interconnect products, semiconductor products and component test products. The interconnect, semiconductor and component test products are sold primarily to manufacturers of electronic components and are used to drill, cut, trim, ablate, test and mark features that improve the yield or functionality of the component. Micromachining products are sold primarily to manufacturers of end devices across multiple industries and are used primarily to drill, cut or mark features on a variety of materials, generally on the casing or external surface of the end device. In addition, micromachining products tend to serve markets that require fewer features, less stringent design requirements, and lower cost. The Company uses U.S. GAAP for segment reporting, consistent with the accounting policies of the consolidated entity. Segment disclosures are presented to the gross profit level as this is the primary performance measure for which the segment management are responsible. Corporate and other charges include amortization of acquired intangible assets, stock-based compensation, restructuring and other costs. Selling, general and administrative and other operating expenses are managed at the functional and corporate levels, and because allocation to the market segments would be arbitrary, have not been allocated to the market segments. See the consolidated statements of operations for reconciliations from gross profit to income before taxes. These reconciling items are not included in the measure of profit and loss for each reportable segment. In the quarter ended July 2, 2016 , we revised the method we use to determine segment gross margin amounts used by the CODM. Previously the profit on the laser (or more specifically, the difference between an estimated third-party purchase price of a similar laser and the cost for the Company to produce these lasers) was associated with only a single segment where the internal lasers were primarily employed or expected to be employed. However, with recent introduction of new products, certain of the Company's internal lasers are now used in both the Component Processing and Micromachining segments. The change in method was made refine the allocation of profit to the segments given this new dynamic, and to ensure that the margin associated with the use of internal lasers is reflected in the profit of the segment generating the third-party sale. No revisions to segment gross margins were made for quarters prior to the current quarter as the changes were deemed immaterial. Net sales by segment were as follows: Fiscal quarter ended (In thousands) July 2, 2016 June 27, 2015 Component Processing $ 43,129 $ 38,284 Micromachining 4,539 4,807 $ 47,668 $ 43,091 Gross profits by segment were as follows: Fiscal quarter ended (In thousands) July 2, 2016 June 27, 2015 Component Processing $ 22,258 $ 14,110 Micromachining 15 1,662 Corporate and other (1,465 ) (395 ) $ 20,808 $ 15,377 Net sales by geographic area, based on the location of the end user, were as follows: Fiscal quarter ended (In thousands) July 2, 2016 June 27, 2015 Asia $ 40,448 $ 33,536 Americas 3,018 6,356 Europe 4,202 3,199 $ 47,668 $ 43,091

Restructuring and Cost Management Plans	Restructuring and Cost Management Plans In March 2015, as a part of the plan to streamline manufacturing and development activities, the Company initiated a restructuring plan that included the closure of the assembly plant and development center located in Chelmsford, Massachusetts, which was part of the Component Processing segment. The original estimated completion date of the plan was the end of fiscal 2016 at a total estimated pre-tax cost of $ 5.5 million . There were no net restructuring costs incurred related to the above mentioned restructuring plan in the first quarter of 2017 . Since the inception of the plan, $5.8 million have been recognized in restructuring costs. The plan was effectively complete as of the end of the fourth quarter of 2016. Included in these costs were write-offs of leasehold improvements associated with the abandoned manufacturing facility, employee severance and related payments, and other wind-down costs. The Company expects to pay the remaining costs and accrued expenses related to the leased facility until December 2019, which is the end of the lease term. At July 2, 2016 and April 2, 2016 , the amount of unpaid restructuring costs included in accrued liabilities was $0.5 million and $0.8 million , respectively.
