Tube glass cutting method and cutting device, and tube glass product manufacturing method
16 Dec 19
With a method of cutting a tube glass (G1) according to the present invention, the tube glass (G1) is irradiated with laser light (L) having a focal point (F) adjusted to an inside of the tube glass (G1), to thereby form an inner crack region (C1) including one or more cracks in a portion of the tube glass (G1) in a circumferential direction of the tube glass (G1) through multiphoton absorption that occurs in an irradiation region of the laser light (L).
