We report a high-repetition-rate, singly resonant optical parametric oscillator based on the nonlinear crystal LiB{sub 3}O{sub 5}, which is synchronously pumped by a continuous train of picosecond pulses from a self-mode-locked Ti:sapphire laser. Under temperature-tuned noncritical type I phase matching, total average near-infrared output powers of 90 mW at a repetition rate of 81 MHz have been generated over a signal (idler) tuning range of 1.374--1.530 {mu}m (1.676--1.828 {mu}m). Without dispersion compensation, transform-limited signal pulses with durations of 520--780 fs have been obtained at 1.2 times threshold for 1.8-ps input pump pulses.
