摘　　要：激光倍频技术是将频率为ω的光,通过晶体中的非线性作用,经过倍频和谐波从激光腔输出的激光包括多个频率的激光。然而,实际应用中需要单频率的激光,所以有必要设计一套分光系统将多频率输出的激光以单频激光输出。介绍了应用多层介质膜反射与透射的原理,设计一套分光系统将波长1064nm的激光器经倍频和三次谐波输出的包含有波长1064、532、355nm的激光分开,并分别以1064、532、355nm的激光输出,以满足不同应用的需要。Laser frequency doubling technology is using ω frequency of the light, which is under the role of non-linear in lens and through the frequency doubling and harmonic, to output laser from the laser cavity, including a number of frequencies of the laser. So it is necessary to design an optical splitting system to separate the multi-frequency laser into a single frequency laser in the result of the need for a single frequency laser in practical application. This article describes the application of the reflect...
