title: Monolithic MgO:LiNbO(3) doubly resonant optical parametric oscillator pumped by a frequency-doubled diode-laser-pumped Nd:YAG laser.
abstract: We have demonstrated a monolithic MgO:LiNbO(3) doubly resonant optical parametric oscillator (OPO) using an allsolid- state pump. The pump laser was a single-axial-mode monolithic Nd:YAG nonplanar ring oscillator whose diode-laser pump was modulated at 325 kHz to produce relaxation oscillation spikes to higher peak powers at 1.06 microm that were frequency doubled in a resonant cavity to 532 nm. Pump depletions for the OPO of greater than 60% were observed when pumping six times above the calculated 40-mW threshold. The OPO output was temperature tuned from 1.01 to 1.13 microm, producing single-axial-mode output over much of the range. By changing the voltage applied across the OPO, the output wavelength was scanned as much as 11 nm in 310 V.
