| 摘 要： | 从激光晶体低增益谱线的运转机理出发,对LD泵浦NdYAG,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.

| Abstract: | Optical thin films for LD-pumped Nd:YAG/LBO yellow laser at 556nm are presented in this paper. To achieve 1 112 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 the 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. |
