Abstract

Passively Q-switched green output with Cr4+:YAG as saturable absorber and PPMgLN as the frequency doubling crystal was realized in a compact diode end-pumped Nd:YVO4 laser. The green light output power, pulse width, pulse repetition rate, pulse energy and peak power with three Cr4+:YAG of different initial transmissions were investigated. The maximum average output power was 1.2 W at the pump power of 4.0 W and the maximum conversion efficiency was 30% with the Cr4+:YAG of 90% initial transmission. The maximum pulse energy and minimum pulse width were 10.9 μJ and 12 ns with the Cr4+:YAG of 75% initial transmission.
