Abstract

A novel, practical, eye-safe solid state laser is described in this paper. Using adjustfree solid state laser with heat conductive cooling element, Ce-Nd:YAG materials, directional prism resonator and Cr4+:YAG passive Q-switch as the pump source for OPO, and with overlapped self-collimation structure, laser energy of 10.5mj, wavelength of 1.57 µ m, pulse width of about 6.3ns and beam divergence of 5mrad were obtained. Also, optical axes was steady under the condition that laser was operated for 30~60 seconds at 5Hz repetition rate.
