Paper Abstract

An efficient single-pass pumped extracavity singly-resonant optical parametric oscillator at 1.57μm eye-safe range using a non-critically phase-matched KTP crystal is reported. The pump source is a diode pumped Gaussian unstable resonator Nd:YAG laser with the high beam quality of M2=1.8. The signal energy of 65mJ with the pulse width of 9ns is obtained under the input pump pulse of 196mJ 12ns. This result provided a clear demonstration that very high pump-to-signal energy conversion (up to 33.2%) can be achieved from an extracavity OPO even by single-pass pumped method. The repetition rate range of the all-solid-state OPO device is 30Hz.
