摘要: 使用掺钕材料作为激光增益介质，再辅以腔内倍频技术，可以高效、稳定的获取多个波段的可见光输出，是全固态激光器的重要发展方向。本文使用Nd:YAG作为激光增益介质，使用YVO4作为拉曼介质，再辅以KTP作为倍频介质，搭建了能够稳定输出588 nm黄光激光输出的腔内倍频声光调Q拉曼激光器。当脉冲重复率为10 kHz，泵浦功率为7.36 W时，得到了最高的输出功率为389 mW，此时从LD到黄光的光–光转换效率为5.3%。
Abstract: Using neodymium-doped materials as laser gain media, combined with intracavity frequency-doubling technology, enables efficient and stable visible light output across multiple wavelength bands, making it a key development direction for all-solid-state lasers. In this study, an intracavity frequency-doubled acousto-optic Q-switched Raman laser was constructed using Nd:YAG as the laser gain medium, YVO₄ as the Raman medium, and KTP as the frequency-doubling medium, achieving stable yellow laser output at 588 nm. At a pulse repetition frequency of 10 kHz and a pump power of 7.36 W, the highest output power of 389 mW was obtained, with an optical-to-optical conversion efficiency of 5.3% from the LD to the yellow light.
