The frequency-doubled output of a high-power passively Q-switched Nd:YAG microchip laser has been used to pump a KTP doubly resonant miniature monolithic Fabry-Perot (microchip) optical parametric oscillator (OPO). The OPO operated with 20% conversion efficiency, generating 8.4 mu J of 1.064-mu m radiation in 600-ps pulses, with excellent mode quality and pulse-to-pulse stability. This is the most compact OPO system yet demonstrated, generating the shortest pulses reported for an OPO pumped with Q-switched pulses. This technology makes it possible to obtain miniature optical system operating at any wavelength throughout the near IR, visible, and UV.
