Abstract: | We present in this paper a highly stable and efficient KTP-based intracavity optical parametric oscillator with a diode-end-pumped
Nd:YVO4/Cr:YAG passively Q-switched laser. At the incident diode pump power of 4 W, the signal (1.57 μm) and idler (3.29 μm) average
output powers up to 580 and 100 mW, respectively, have been achieved. The corresponding conversion efficiency from the input
diode pump power to the output signal power is 14.5%, while that to the total OPO output (signal+idler) reaches 17%. To the
best of our knowledge, these are the highest conversion efficiencies reported to date. After more than four hours of investigation,
the OPO power stability better than 2% has been obtained. In addition, efficient cavity dumping of the IOPO has inevitably
led to the short pulse duration (1.6 ns) and high peak power output (8.3 kW) at the signal wave. Additionally, the amplitude
and repetition rate fluctuations of the signal pulses are well within 5%.
