【Abstract】 In this paper, the influence of the primary resonator′s stability on the Q switch is experimentally studied, the results have shown that unstable primary resonator with high diffraction losses can improve the Q switch effect of phase conjugation cavity laser. The characteristic of output pulses from two types of phase conjugation cavity lasers with H 2O and CS 2 SBS medium, was compared and analyzed.更多还原
