Utility
High-power, single-mode fiber sources
13 Jan 20
An optical apparatus includes one or more pump sources situated to provide laser pump light, and a gain fiber optically coupled to the one or more pump sources, the gain fiber including an actively doped core situated to produce an output beam, an inner cladding and outer cladding surrounding the doped core and situated to propagate pump light, and a polymer cladding surrounding the outer cladding and situated to guide a selected portion of the pump light coupled into the inner and outer claddings of the gain fiber.

Utility
Fiber with depressed central index for increased beam parameter product
30 Dec 19
A method includes generating a multimode laser beam having an initial beam parameter product (bpp) and directing the multimode laser beam to an input end of a fiber so as to produce an output beam at an output of the fiber with a final bpp that is greater than the initial bpp.
