| Abstract: | Laser beam quality is a current interesting topic.The laser beam quality's evaluating criterion for different application purposes is generally different.Several typical evaluation methods for the laser light beam quality at present are introduced.The appropriate areas and rationality for various standard of laser beam quality are also analyzed in details respectively.Then,some practical requirements for the laser beam quality and related characteristic parameters are studied. |
