532 nm pumped optical parametric oscillator using periodically-poled stoichiometric LiTaO/sub 3/

A pulsed tunable optical parametric oscillator using periodically-poled stoichiometric lithium tantalate pumped at 532 nm is reported. The tuning range achieved was from 0.65 /spl mu/m to 2.97 /spl mu/m and the photon conversion efficiency was 40%.
