摘要

Highly efficient passively Q-switched Yb:YAG ceramic laser with Cr4+:YAG crystal as saturable absorber is achieved.Maximum average output power of 0.96 W is obtained when the absorbed pump power of 3.8 W is used;corresponding optical-to-optical efficiency is about 25％.The slope efficiency is 30％.Laser pulses at 1030 nm with pulse energy of 107 μJ and pulse width of 9 ns are achieved at repetition rate of 9 kHz,with corresponding peak power of 11.9 kW.Meanwhile the effects of absorbed pump power on the characteristics of passively Q-switched laser pulses are investigated systematically.
