摘要：

A high-energy and high-efficiency 2 μm nanosecond optical parametric oscillator(OPO) with excellent energy stability is reported. The cavity adopts a plane–plane configuration with two potassium titanyl phosphate(KTP) crystals inserted using a spatial walk-off compensated orientation. The KTP-OPO is pumped by a 1064 nm Nd:YAG Q-switched laser at a repetition rate of 10 Hz and produces a maximum pulse energy of 162.6 m J at a pump energy of 431 m J, corresponding to an optical conversion efficiency of 37.7% and a slope efficiency of 45.2%. The energy stability shows a record root mean square(RMS) of0.4% over 30 min. To our knowledge, this represents the highest 2 μm pulse energy achieved via the 1 μm laser-pumped KTPOPO scheme, which could be an excellent laser source for driving extreme ultraviolet(EUV) radiations in the subsequent demonstration experiments.
