We describe an intracavity frequency-doubled high repetition-rate picosecond optical parametric oscillator for the visible based solely on the nonlinear crystal LiB3O5 and synchronously pumped by a self-mode-locked Ti:sapphire laser. Under temperature-tuned noncritical type I and type II phase matching, average visible output powers of 320 mW have been generated at an 81-MHz repetition rate. With the available mirror set, continuous tuning from 584 to 771 nm is demonstrated for a range of phase-matching temperatures. Transform-limited pulses with durations of 840-880 fs have been obtained across the visible range for pump pulse durations of 1-1.2 ps. (C) 1996 Optical Society of America
