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.
