Abstract: A resonator for 1.444 mm Nd:YAG laser was designed, and 1.444 mm laser was obtained, the maximum static-state output energy was 310 mJ, electric-optics conversion efficiency was 0.56% and slope efficiency was 0.81% when the pump energy was 55 J. The 1.444 mm Q-switched laser was obtained, whose energy was 18 mJ and pulse width was 150 ns when the pump energy was 24 J. The CCD image showed that the energy distribution of the obtained laser was uniform and the divergence angle was 0.8 mrad.-
