本文描述了一种由调q Nd:YAG激光器泵浦的非临界相位匹配KTP晶体的单谐振光学参量振荡器（OPO）。在人眼安全范围内，波长为1.58 mm的信号脉冲能量高达8.1 mJ。基于调q激光器的速率方程和非线性晶体中参量相互作用的耦合方程，建立了腔内激光泵浦OPO （IOPO）的简单模型。在1.5倍脉冲IOPO阈值下，分别计算和检测5和6 ns的信号脉冲宽度。©2001
We describe a singly resonant optical parametric oscillator (OPO) using a noncritically phase-matched KTP crystal, intracavity- pumped by a Q-switched Nd:YAG laser. Signal pulse energy of as much as 8.1 mJ in the eye-safe range at 1.58-mm wavelength was coupled out of the cavity. We have elaborated a simple model of an intracavity laser- pumped OPO (IOPO), based on the rate equations for the Q-switched laser combined with the coupled equations for the parametric interaction in the nonlinear crystal. At 1.5 times pulsed IOPO threshold, signal pulse widths of 5 and 6 ns were calculated and detected, respectively. © 2001
