摘要
从激光晶体低增益谱线的运转机理出发,对LD泵浦Nd∶YAG,LBO腔内倍频556 nm激光器所使用的光学薄膜进行了研制。在激光反射镜的设计上,为保证基频光1 112 nm的高效振荡,并获得高的倍频556 nm激光输出,对膜系要求进行了深入分析。采用离子束反应溅射和离子辅助沉积的方法,运用时间监控膜厚法成功置备出556 nm激光器所使用的特殊的全介质激光反射膜,在国内首次实现了1 112 nm激光高效振荡,通过LBO腔内倍频,在2 W的LD泵浦功率下获得102 mW 556 nm激光输出。
Optical thin films for LD- pumped Nd ： YAG / LBO yellow laser at 556 nm are presented in this paper. To achieve 1112 nm laser action and output 556 nm yellow laser with high power, the coating design of resonator mirrors was analyzed. The spectrum transmittance/reflectance request was reasonably distributed on tile two resonator facet reflectivity to restrain the other laser lines such as 946 nm, 1 064 nm and 1 319 nm. The dielectric high reflective laser mirrors was achieved by double ion beam sputter technique for the first time, which was controlled by a time-power monitoring method. When the incident pump power was 2 W, CW 556 nm yellow laser output power of 102 mW was obtained.
