【Abstract】 Due to the requirement of laser conditioning system of ICF drive. A Nd : YAG laser system with high power and high beam quality is developed. Compared to current c ommon laser system, it has an apparent improvement in temporal shape and beam quality. The s ystem applies several technologies and teaches as following: a single longitudinal mode oscillator wit h a passive Q-switch; SBS pulse compressing technology; SBS pulse phase-conjugation technology; image relay technology and high efficient pumping cavity. Its main technology indexes are listed as pul se width 3ns ,energy 1.1J,far field diverge angle 0.3mrad,repitition frequency 10Hz.更多还原
