We report a tunable, narrow-linewidth UV laser based on intracavity second-harmonic generation in a red semiconductor disk laser. Single-frequency operation is demonstrated with a total UV output power of 26 mW. By servo-locking the fundamental frequency to a reference Fabry-Pérot cavity, the linewidth of the UV beam has been reduced to 16 kHz on short timescales and 50 kHz on a 1 s timescale, relative to the reference.
我们报告了一种基于腔内二次谐波产生的可调谐、窄线宽紫外激光器，该激光器采用红色半导体盘激光器。通过对基频进行伺服锁定到参考法布里-珀罗腔，我们实现了单频操作，并获得了 26 mW 的总紫外输出功率。与参考相比，在短时间尺度上，紫外光束的线宽已减小到 16 kHz，在 1 s 时间尺度上减小到 50 kHz。
