High peak power output of a diode-pumped Q-switched and mode locked Nd : LuVO4 with Cr : YAG saturable absorber

Abstract

The Q-switched mode-locked (QML) pulses is demonstrated in a Nd:LuVO4 laser to generate peak power exceeding 400 kW. By the Cr:YAG with initial transmittance T-0=40%, the Q-switching envelope about 30 ns and 6.9 kHz repetition rate is produced and the pulsewidth of CW-ML pulses is about 56 ps.
