Abstract

We report a continuous-wave (cw) 532-nm-pumped singly resonant optical parametric oscillator (SRO) based on periodically poled lithium niobate. The pump source is a commercial 5-W cw diode-pumped, multilongitudinal-mode, intracavity-doubled Nd:YVO4 laser. Using a four-mirror ring SRO cavity and single-pass pumping, we achieved subwatt internal oscillation threshold, 56% quantum efficiency, and output tuning from 917 to 1266  nm.

Schematic diagram of the four-mirror bow-tie ring SRO. The pump was a cw 532-nm 5-W frequency-doubled Nd:YVO4 laser. The cavity utilized two 20-cm radius-of-curvature mirrors (M1, M2) and two planar mirrors (M3, M4). All mirrors were highly reflecting at 900–1000  nm. The PPLN crystal was 53 mm long and 0.5  mm thick and had a grating period of 6.5 µm.

Pump depletion and idler power internal to the PPLN crystal versus pump power internal to the PPLN crystal. To reduce thermal loading of the PPLN at 532  nm, a 50%-duty-cycle mechanical chopper was used to modulate the pump. Pump and idler power levels represent peak power during the chopper cycle.

Output power of the 961-nm signal and the 1192-nm idler versus pump power internal to the PPLN crystal for the output-coupled cavity. A planar R=96% at 961-nm reflector was used as an output coupler for the resonated signal. The pump was modulated with a 50%-duty-cycle chopper, and power levels represent peak power during the chopper cycle.

Wavelength tuning versus temperature for the SRO. The 6.5-µm-domain-period PPLN was heated from 200 to 260 °C, tuning the output from 917 to 1266  nm. Two mirror sets were utilized, one set optimized for off-degenerate tuning (circles) and a second set optimized for near-degenerate tuning (crosses). Double resonance was observed at phase matching very near degeneracy. Two theoretical tuning curves are calculated from the temperature-dependent Sellmeier equations for the index ne in congruent LiNbO3 of Edwards and Lawrence11 (dashed curve) and Jundt12 (solid curve).
