Abstract

We report a high-average-power acousto-optic (AO) Q-switched intracavity frequency-doubled red laser based on a high-efficiency light-emitting-diode (LED) pumped two-rod Nd,Ce:YAG laser module. Under quasi-continuous wave operation conditions, a maximum output power of 1319.08 nm wavelength was achieved at 11.26 W at a repetition rate of 100 Hz, corresponding to a maximum optical efficiency of 13.9% and a slope efficiency of 17.9%. In the active Q-switched regime, the pulse energy of the laser was as high as 800 μJ at a repetition rate of 10 kHz with a pulse width of 1.5 μs. Under non-critical phase-matched KTP crystal conditions, an average power of 2.03 W of 658.66 nm through intracavity frequency-doubling was obtained at a repetition frequency of 10 kHz with a duration of 1.3 μs, and the M ² factor was measured to be about 5.8. To the best of our knowledge, this is the highest average power of an LED-pumped AO Q-switched 1319 nm laser and intracavity frequency-doubled red laser reported to date.

可产生 2W Q 开关红光的 LED 侧泵浦腔内倍频 Nd、Ce：YAG 激光器

我们报告了一种基于高效发光二极管（LED）泵浦双杆 Nd、Ce：YAG 激光模块的高平均功率声光（AO）Q 开关腔内倍频红激光器。在准连续波工作条件下，以 11.26 W 的功率和 100 Hz 的重复频率实现了 1319.08 nm 波长的最大输出功率，相应的最大光学效率为 13.9%，斜率效率为 17.9%。在主动 Q 开关模式下，激光脉冲能量高达 800 μJ，重复频率为 10 kHz，脉冲宽度为 1.5 μs。在非临界相位匹配 KTP 晶体条件下，通过腔内倍频，在重复频率为 10 kHz、持续时间为 1.3 μs 时获得了 2.03 W 的 658.66 nm 平均功率，测得 M2 因子约为 5.8。据我们所知，这是迄今为止报道的平均功率最高的 LED 泵浦 AO Q 开关 1319 nm 激光器和腔内倍频红激光器。
