| Abstract: | This paper presents the beam mode,some methods for evaluating beam quality. As put forward by International Organization forStandardization, here the method to use beam propagation factor M for evaluating beamquality has been dis-cussed. The influences of laser beam quality and the thermal effect of lens oii the laser welding,cutting and laser processing are also described. |
