The eye-safe laser is introduced with a wide temperature working and MW-level peak power. The semiconductor laser cross-pumped Nd∶YAG 1.06 μm laser is used as the pump source. The eye-safe laser output is realized by an intracavity pumped non-critical phase KTP optical parametric oscillator. The laser performance test results show that when the frequency is 5 Hz, the average laser output energy is 56 mJ, the pulse width is 2.02 ns, the peak power reaches 28 MW, and the laser divergence angle is about 5 mrad. Under the environmental conditions of -45~65 ℃, the laser energy changes by 3.8%, and it can work for a long time in the high and low temperature environment. The laser has a compact structure and high reliability. The device has been produced nationwide. It has been engineered to be used in laser ranging and laser imaging.
