摘要

We demonstrate a temperature tunable infrared optical parametric oscillator (OPO) based on periodically poled LiNbO3 (PPLN) pumped by an acousto-optically Q-switched cw-diode-end-pumped Nd:YVO4 laser with the signal output from 1.48μm to 1.54μm by tuning the work temperature from 60℃ to 250℃ and the maximum average signal power (1500nm) of 137mW. We report the demonstration of the sum frequency of the pump and idler in a single-grating PPLN crystal. In addition, we present the theoretical analysis of the signalwavelength change rate with the changing temperature for a quasi-phase matching OPO, which is in good agreement with our experimental results.
