Method and Device for processing materials with a Pulsed laser beam generated by a laser Fiber

摘要

Procedure for processing materials with a Laser Beam (L) generated by a Pulsed Fiber laser (4),Characterized by an optical switching element (16) Mounted below the Fiber laser (4) externallyWhen the switching element (16) arranged in the Optical Path of the laser beam (L) closes and passed to a State in which the laser beam is transmitted as soon as l(P) to output power of the laser beam (L) is below a Predetermined value.
