摘要
An efficient intracavity single-resonant optical parametric oscillator （OPO） at 1.571-μm eye-safe range using a non-critically phase-matched KTP crystal is reported. The OPO is excited by a diode side-pumped electro-optic Q-switched Nd：YAG laser at 1.064 μm. Signal pulse of 97 mJ and 3.56 ns is obtained under the input electric energy of 2.3 J, corresponding to a slope efficiency of 4.2%, and a repetition rate range of 1-30 Hz. OCIS codes： 190.2620, 140.3480, 140.3540, 140.0140.
