摘要

采用非稳腔光参量振荡(OPO)研制了千赫兹重复频率人眼安全波段全固态激光器。激光器采用电光调Q方式、脉冲激光二极管(LD)侧面泵浦Nd:YAG激光晶体实现了高光束质量的1.064 μm基频激光。光参量振荡部分采用Ⅱ类非临界相位匹配KTP晶体, 为了获得较好的光束质量, OPO谐振腔采用平凸非稳定谐振腔结构, 实现了千赫兹重频、窄脉冲1.57 μm波段激光输出。在脉冲激光二极管泵浦电流为125 A、电光调Q重复频率为1 kHz时, 1.57 μm激光输出最大平均功率达到了4.67 W, 激光脉冲宽度为4.3 ns, 功率不稳定度为3%, 激光泵浦阈值约为45 A。

Abstract

The eye-safe kilohertz repetition rate solid-state laser was developed by using the OPO of unstable resonator. Using pulse LD side-pumping Nd:YAG laser crystal and electro-optical Q-switched techniques, the laser achieved high beam quality of 1.064 μm fundamental frequency light. The II type noncritical phase-matching KTP crystal was adopted in optical parametric oscillation. In order to get high beam quality, the OPO cavity made use of plane-convex unstable resonator structure. The laser system could operate stably at the wavelength of kilohertz repetition rate 1.57 μm. When the pumping current of LD was 125 A and the electro-optical Q-switched repetition rate was 1 kHz, the maximum average output power of 1.57 μm laser was 4.67 W and the pulse width of the output laser was 4.3 ns, the power instability of 1.57 μm was 3%. The laser pumping threshold was about 45 A.
