Abstract

A low-threshold (106-mW) singly resonant optical parametric oscillation (OPO) was demonstrated in near-stoichiometric periodically poled LiTaO₃. A simple oscillator, with a two-mirror cavity was pumped by a Nd:YVO₄ laser, had an output of 628 mW at 1.1 W pump and was tuned over 1.53-1.63 μm (signal) and 3.06-3.49 μm (idler). We obtained a slope efficiency of 65 % with 35-mm device length at 175 °C. Average ratios of domain width and poling characteristics were described.
