描述了用闪光灯抽运的Q开关Nd:YAG激光器在1.064μm抽运以KTP为基础的光学参量振荡器的性能和进展。实验研究了光学共振腔构型对光学参量振荡器(OPO)性能的影响。用稳定短腔KTP光学参量振荡器得到了I.57μm、40mJ输出能量。在近2倍振荡阈值之上工作获得效率(闪光灯输入能量与光学参量振荡器信号波输出能量之比)0.55％,在5~50Hz范围内输出脉冲能量与闪光灯输入能量的关系不变。
Describes the performance and progress of flash-pumped Q-switched Nd: YAG lasers on a KTP-based optical parametric oscillator at 1.064 μm. The effect of optical cavity configuration on the performance of optical parametric oscillator (OPO) was investigated experimentally. With a stable short-time KTP optical parametric oscillator I.57μm, 40mJ output energy. 0.55% of working efficiency (the ratio of flash input energy to optical parametric oscillator signal wave output energy) is obtained at nearly 2 times the oscillation threshold, and the relationship between the output pulse energy and the input energy of the flash lamp is unchanged in the range of 5 ~ 50 Hz.
