Abstract

With Cr:YAG as a saturable absorber, a passively Q-switched self-frequency-doubled (SFD) laser based on a trigonal Nd:CaNbGaSiO (Nd:CNGS) silicate crystal was demonstrated for the first time. The maximum average output power at 532 nm was 16.2 mW, and the corresponding pulse repetition frequency, single pulse energy, pulse duration and peak power were 2.25 kHz, 7.2 μJ, 13.7 ns, 0.53 kW, respectively. We also present a rate-equation model of such a passively Q-switched SFD laser showing a good agreement with the experiment. Nd:CNGS is a promising pulse SFD material for miniature all-solid-state visible light sources.

摘要

首次展示了以Cr:YAG作为可饱和吸收体、基于三角晶系Nd:CaNbGaSiO（Nd:CNGS）硅酸盐晶体的被动调Q自倍频（SFD）激光器。532nm处的最大平均输出功率为16.2mW，相应的脉冲重复频率、单脉冲能量、脉冲持续时间和峰值功率分别为2.25kHz、7.2μJ、13.7ns、0.53kW。我们还给出了这种被动调Q SFD激光器的速率方程模型，其与实验结果吻合良好。Nd:CNGS是用于微型全固态可见光源的一种很有前景的脉冲SFD材料。
