Paper Abstract

We report on optical parametric oscillator (OPO) based on 2 mm-thick periodically poled Mg-doped stoichiometric LiTaO3 (PPMgSLT) pumped within the cavity of a Q-switched diode-pumped Nd:YAG laser of high average power that operates at 10 kHz repetition rate. We have obtained 9 W of 2-μm output at the diode current of 21 A from a near-degenerate phase-matched OPO using simple cavity configuration. We also found it has a good long-term stability with such an output of high average power for more than an hour. The intensity profile and measured M2 of 2-μm output beam were circularly symmetric and ~7.
