| Abstract: | In thls paper,the size and position of a single convex lens and the output aperture of multimode fiber are calculated and discussed. Small focal spot can be obtained by use of convexlens only for the high power Nd:YAG laser transmitted through multimode fiber.The method has some actual meanings in many aspects of laser processing. |
