摘　　要：通过双波长振荡的理论计算,初步确定了黄激光的基频光1123 nm激光腔的镀膜参数。根据理论计算结果,对谐振腔进行了优化设计,采用选择性镀膜方式,对增益系数较大的1 064、946以及1 319 nm激光进行抑制使其在腔内不能增益起振,同时使得1 123 nm激光可以较容易地在腔内增益起振,采用50 W功率808 nm波长的半导体模块进行泵浦,获得了功率为6.3 W的1123 nm波长激光输出。通过对561 nm激光输出镜镀膜参数的设计,采用KTP晶体倍频,最终获得了3.5W功率的561 nm黄激光输出。In this paper, the reflectivity parameters of 1 123 nm laser cavity were preliminarily calculated based on the theory of simultaneous dual wavelength laser, and the optimum laser resonant cavity was designed. In the cavity, 1064 nm, 946 nm, 1319 nm lasers were restrained and 1 123 nm laser was enhanced through designing the selective reflectivity parameters of the mirrors, 6.3 W 1 123 nm laser was obtained with 50 W 808 nm side-pumped diode laser. Then, the selective reflectivity parameter of 561 nm output mirror was designed, 3.5 W 561 nm yellow laser beam was obtained by intracavity doubling the frequency of 1 123 nm laser with KTP crystal.
