Abstract

An intracavity KTiOPO4 (KTP) optical parametric oscillator (OPO) pumped by a simultaneously Q-switched and mode-locked (QML) Nd:Gd3Ga5O12 (Nd:GGG) laser with an acousto-optic modulator (AOM) and a Cr4+:YAG saturable absorber is presented. A minimum mode-locking pulse duration underneath the Q-switched envelope was evaluated to be about 290 ps. A maximum QML output power of 82 mW at the signal wavelength of 1570 nm was achieved, corresponding to a maximum mode-locked pulse energy of about 5.12 μJ. The M2 values were measured to be about 1.3 and 1.5 for tangential and sagittal directions using knife-edge technique.
