Abstract

By employing SrWO4 as Raman active media and ceramic Nd:YAG as laser gain media, a diode-pumped actively Q-switched Raman laser is demonstrated. Single or multiple wavelength first-stokes Raman generations at 1238 and 1252 nm are achieved. To our knowledge, this is the first Raman laser demonstration based on fundamental wavelengths around 1.1 μm. Maximum output powers are 1.02 W at single 1252 nm wavelength, 1.08 W at single 1238 nm wavelength, and 442 mW at multiple wavelengths of 1252 and 1238 nm, corresponding to optical-to-optical conversion efficiencies of 4.78%, 4.95%, and 2.54%, respectively.

摘要

通过采用SrWO4作为拉曼活性介质，陶瓷Nd:YAG作为激光增益介质，演示了一种二极管泵浦的主动调Q拉曼激光器。实现了在1238和1252 nm处的单波长或多波长一阶斯托克斯拉曼产生。据我们所知，这是基于1.1μm左右基波波长的首次拉曼激光器演示。在1252 nm单波长处的最大输出功率为1.02 W，在1238 nm单波长处为1.08 W，在1252和1238 nm多波长处为442 mW，对应的光光转换效率分别为4.78%、4.95%和2.54%。
