Abstract

A diode-pumped passively Q-switched Nd:YVO4 green laser with a periodically poled KTP and Cr4+:YAG saturable absorber is realized. The dependences of pulse repetition rate, pulse energy, pulse width, and peak power on incident pump power are measured for the generated green-light pulses. A rate-equation model is introduced to theoretically analyze the results obtained in the experiment, in which the spatial distribution of the intracavity photon density is taken into account. The numerical solutions of the rate equations agree with the experimental results.

摘要

实现了一种带有周期性极化KTP和Cr4+:YAG饱和吸收体的二极管泵浦被动调Q Nd:YVO4绿色激光器。针对产生的绿光脉冲，测量了脉冲重复率、脉冲能量、脉冲宽度和峰值功率对入射泵浦功率的依赖性。引入了速率方程模型对实验结果进行理论分析，其中考虑了腔内光子密度的空间分布。速率方程的数值解与实验结果相符。
