Abstract

We describe a source of visible (532 nm) radiation for pumping picosecond optical parametric oscillators. Picosecond pulses generated by a passively Q-switched Nd:YAG oscillator are amplified in two amplifier stages and frequency doubled in a KDP crystal cut for type I or type II phase-matching. Trains of pulses of 7 - 11 mJ over-all energy are generated, single pulse energy is 450 - 600 (mu) J and pulsewidth about 40 ps.
