Paper Abstract

A compact and efficient diode-array pumped high power passively Q-switched N:YAG laser has been used to pump a quasi-phase-matched PPMgLN optical parametric oscillator. Stable laser pulses of duration of 3.0 ns, energy of 69.3 micro-joule and repetition rate of 7.0 kHz were generated from the passively Q-switched Nd:YAG laser at an incident pump power of 6.8 W. The periodically poled MgO-doped LiNbO3 has an interaction length of 30 mm and a thickness 0.5-mm. The OPO generates signal and idler wavelengths tunable in the range of 1.48-1.59 micron and 3.78-3.21 micron, respectively, by using seven different poling periods. The measured signal output power was approximately 140 mW at an average incident pump power of 485 mW. The OPO was operated at around room temperature and no photorefractive effect was found.
