摘要

采用电光调Q脉冲Nd:YAG激光的二次谐波(532nm)抽运温度调谐的MgO:LiNbO3晶体光学参量振荡器,调谐范围达800nm～1750nm。在单谐振运转条件下,抽运阈值为21.5mJ/pulse,最大抽运能量为58mJ时输出为6.45mJ,在大信号情况下的能量转换效率达11%,输出线宽1nm左右。

Abstract

A temperature tuned MgO:LiNbO3 optical parametric oscillator (OPO) pumped by a Nd:YAG-SHG pulse laser with the wide tunable range of 800 nm～1750 nm is demonstrated. At the singly resonant forms, the oscillation threshold is 21.5 mJ, and the highest output energy is 6.45 mJ when pumped by the highest energy of 58 mJ. The OPO conversion efficiency of energy was 11%. Linewidth of the OPO signal light is near 1 nm.
