| Abstract: | The experimental results of singly resonant KTP optical parametric oscillator pumped by second harmonic of GCR-190 Nd:YAG laser system are reported in this paper. The KTP OPO was tunable in the eye-safe wavelengths range of 1.53～1.84 μm and 0.75～0.82 μm in the near-infared region. In this experiment, the largest energy of 130 mJ and highest energy conversion efficiency of 16.9% with repetition rate of 10 Hz were achieved, while the pump laser was introduced into the oscillator along the direction vertical to cavity axis. At the same time, the beam quality and linewidth of KTP OPO were measured. |
