摘要：

We report a nanosecond singly resonant intracavity optical parametric oscillator (OPO) emitting at 1535 nm. This OPO is based on a type II non-critically phase-matched KTiOAsO4 (KTA) crystal. A diode-side-pumped acousto-optically Q-switched Nd : YAG laser is used as the pumping source. With a laser diode power of 96.3 W and a pulse repetition rate of 10 kHz, we obtain a signal power of 2.54 W, corresponding to an optical-to-optical conversion efficiency of 2.6%. This is the highest efficiency reported for intracavity KTA OPOs with diode-side-pumping configurations. The pulse width is 5.01 ns and the peak power is 50.7 kW. The stability of the signal power is measured to be better than 3% during 2 h operation.
