摘要

在这项研究中，我们展示了一种基于led泵浦电光（E-O）调q Nd:YAG激光器的腔内倍频激光器，具有高峰值功率和窄脉冲宽度。在调q工作模式下，在200 Hz的重复频率下，在1064 nm处获得了4.35 mJ脉冲能量的最大输出，持续时间为88 ns，峰值功率为50 kW。通过优化KTP晶体的入射角以满足非临界相位匹配条件，在200 Hz的重复频率下，532 nm的绿色激光输出脉冲能量为1.55 mJ，持续时间为46 ns，腔内倍频输出峰值功率为33.7 kW。据我们所知，这是迄今为止报道的led泵浦E-O q开关1064和532纳米激光器的首次演示。

Narrow Pulse Width Green Laser Based on LED-Pumped Electro-Optically Q-Switched Nd:YAG Laser

In this study, we demonstrate an intracavity frequency-doubled 532-nm laser with a high peak power and narrow pulse width based on an LED-pumped electro-optically (E-O) Q-switched Nd:YAG laser. In the Q-switched operation mode, a maximum output of 4.35 mJ pulse energy at 1064 nm was obtained at a repetition rate of 200 Hz with a duration of 88 ns and a peak power of 50 kW. By optimizing the incidence angle of the KTP crystal to satisfy the noncritical phase-matching condition, the output pulse energy for the green laser at 532 nm was 1.55 mJ at a repetition rate of 200 Hz with a duration of 46 ns and a peak power of 33.7 kW by intracavity frequency doubling. To the best of our knowledge, this is the first demonstration of LED-pumped E-O Q-switched 1064- and 532-nm lasers reported to date.
