Efficient high-peak-power and high-repetition-rate eye-safe laser using an intracavity KTP OPO

摘要

An efficient high-peak-power and high-repetition-rate intracavity KTP optical parametric oscillator pumped by a Q-switched Nd:YVO4 laser is demonstrated. We achieved 1.5 W output power of 1.5 mu m at 10 kHz repetition rate with the pulse duration of 6 ns. The maximum peak power of 25 kW and the maximum pulse energy of 150 mu J have been obtained. The maximum conversion efficiency of 9.5% is achieved with respect to a laser diode power of 10.5 W.
