摘要

我们报告了一种基于从 2F5/2 电平到 2F7/2 电平转变的准三电平激光泵浦 Ca4GdO(BO3)3 (Yb:GdCOB)可调谐激光器。通过调节 902 nm 的泵浦功率，获得了近红外波长从 1030 nm 到 1036 nm 的连续波 Yb:GdCOB 激光器。最高调谐功率为 2.5 W，斜率效率为 19.9%。据我们所知，这是第一台通过调节泵浦功率实现的可调谐掺钕镓硒激光器。这项工作提供了一种结构紧凑、简单的产生可调谐固体激光器的新方法。

Quasi-three-level laser pumped Yb:GdCOB tunable laser from 1030 to 1036 nm

We report a quasi-three-level laser pumped Ca₄GdO(BO₃)₃ (Yb:GdCOB) tunable laser based on the transition from the ² F _5/2 level to the ² F _7/2 level. By adjusting the 902 nm pump power, a continuous waves Yb:GdCOB laser was obtained with the near-infrared wavelengths shifting from 1030 nm to 1036 nm. The highest tuning power of 2.5 W was achieved with a slope efficiency of 19.9%. To our knowledge, it is the first tunable Yb:GdCOB laser to be realized by adjusting the pump power. This work provides a novel method to generate tunable solid-state lasers with a compact and simple structure.
