Abstract

We report a high-power diode-double-end-pumped Q-switched Nd:YVO4 red laser through intracavity frequency-doubling with a type-I critical phase-matched LBO crystal. At a repetition frequency of 21.72 kHz, a maximum average output power of 10.2 W at 671 nm was measured to while the incident pump power was 78.4 W, the corresponding optical conversion efficiency was 13.0%, with a pulse width of about 94 ns and a pulse energy of 469.6 muJ, the peak power was 5.0 kW. At an average output power around 9.6 W a power stability better than 2.3% was maintained for half an hour.

摘要

我们报道了一种通过腔内倍频，采用I型临界相位匹配的LBO晶体实现的高功率二极管双端泵浦调Q Nd:YVO4红光激光器。在重复频率为21.72kHz时，当入射泵浦功率为78.4W时，测得671nm处的最大平均输出功率为10.2W，相应的光转换效率为13.0%，脉冲宽度约为94ns，脉冲能量为469.6μJ，峰值功率为5.0kW。在平均输出功率约为9.6W时，半小时内功率稳定性优于2.3%。
