We report on the synchronous pumping of an optical parametric oscillator (OPO) using a frequency-doubled, mode-locked, and {ital Q}-switched diode laser pumped yttrium lithium fluoride laser. Using a 1 W pump diode, frequency modulation mode locking, and acousto-optic {ital Q} switching, a pulse envelope of 75 ns duration and 45 {mu}J of energy in 21 ps pulses at 360 MHz repetition rate was obtained. This was frequency doubled in 90{degree} phase-matched MgO:LiNbO{sub 3} with 47% energy conversion efficiency. The doubly resonant OPO based upon temperature-tuned MgO:LiNbO{sub 3} had an energy conversion efficiency of 20% at degeneracy. The tuning range of 983--1119 nm was limited by the mirror reflectivities.
