Abstract

Abstract A diode-pumped actively Q-switched Raman laser employing SrWO4 as Raman active medium and Nd:YAG as laser gain medium is demonstrated. The first-Stokes Raman generation at 1252.4nm based on the fundamental wavelength of 1123nm is achieved for the first time. With a pump power of 20.3W and pulse repetition frequency rate of 5kHz, a maximum output power of 1.1W is obtained, corresponding to an optical-to-optical conversion efficiency of 5.4%, and a corresponding pulse energy and peak power was 220µJ and 3.3kW, respectively.
