Abstract

In a tandem optical parametric oscillator (OPO) a quasiphasematched crystal is fabricated by cascading two or more gratings in series so that the light generated in the first grating undergoes further frequency conversion in the second grating and this approach should make it possible to obtain high-quantum-efficiency conversion from a near-infrared pump to a mid-infrared idler. Self-modelocked Ti:sapphire laser was used as pump source for OPO. The tuning and characterisation data from the OPO and its performance such as threshold and conversion efficiency is discussed.
