OPTICAL PARAMETRIC OSCILLATION IN PERIODICALLY POLED LITHIUM-NIOBATE BASED ON CONTINUOUS-WAVE SYNCHRONOUS PUMPING AT 1.047-MU-M

A singly resonant optical parametric oscillator is reported that uses a periodically poled LiNbO3 crystal and is synchronously pumped by a c w mode-locked 1.047-mu m Nd:YLF laser. Picosecond pulses were tunable from 1.67 to 2.806 mu m. Mean output powers of 120 mW (90 mW) were obt ained for the signal (idler) wave with an overall slope efficiency of 61% at a pump depletion of 75% when the oscillator was operating at th ree times above threshold.
