Considering the specific requirement of reliability of military lasers, a consolidated intracavity eye-safe optical parametric oscillator (OPO) is designed. By using double-directional-prism resonator,Cr44 :YAG passive ^-switch, Ce-Nd^YAG laser rod, noncritical phase matching KTP crystal, 1.57 (j,m OPO laser is obtained with 5.3mJ/pulse of energy, ?I6 ns of pulse width and ?=5mrad of divergence. After continuously working for lmin at the repetition rate of 3Hz, the output energy and optical axis is still stable. It had the characteristics of compact structure and high reliability. |
