Low-threshold picosecond optical parametric oscillation in quasi-phase-matched lithium niobate

By V. Pruneri, S.D. Butterworth and D.C. Hanna


We report a singly resonant optical parametric oscillator in periodically poled lithium niobate. synchronously pumped by the second harmonic of an amplified 10 µs pulse train from a continuous wave mode-locked Nd:YLF laser. Pulses of ~2 ps duration have been generated over the tuning range from 883 to 1285 nm with a typical threshold of 200 mW average power within the 10 µs envelope. The M^2 beam quality factor for the generated signal was ~1.1, indicating absence of any significant photorefractive damage
