KLu(WO₄)₂crystal as the Raman medium in a diode-pumped passively Q-switched Nd:YAG laser

Abstract

A diode-pumped passively Q-switched Nd:YAG/KLu(WO₄)₂ (KLW) Raman laser is presented for the first time. As high as 1.89 W average output power is obtained at the pump power of 15.7 W with the pulse repetition frequency (PRF) of 27.2 kHz, and the corresponding diode-to-Stokes conversion efficiency is 12.0%. The highest pulse energy of 84.0 μJ is obtained. The obtained average output power and pulse energy are much higher than the previously reported results of diode-pumped passively Q-switched Raman lasers.
