Highly efficient diode-pumped actively Q-switched Nd:YAG-SrWO_4 intracavity Raman laser

Abstract

A highly efficient diode-pumped actively Q-switched intracavity Raman laser with SrWO(4) as the Raman-active medium is presented. As high as 23.8% diode-to-Stokes optical conversion efficiency is obtained with an incident pump power of 7.17 W and a pulse repetition rate of 15 kHz.
