Abstract
A high-repetition-rate CW laser diode pumped acousto-optically(AO) Q-switched eye-safe intracavity optical parametric oscillator at 1.57μm with a type-Ⅱ non-critically phase-matched X-cut KTP is experimentally studied.Using a CW laser diode three-side-pumping Nd:YAG module and a QSGSU-6 AO Q-switch,with a single oscillator 1.57μm OPO placed inside the resonator of a Q-switched 1.06μm Nd:YAG laser,the maximum power of 480mW and the maximum peak power of 58.8kW at 1.57μm are obtained with pulse duration about 2.72ns at 3kHz the opto-electronic efficiency is up to 2.6‰.CW laser diode pumped AO Q-switched intracality optical parametric oscillator is a good chice for high-repetition-rate eye-safe laser.
