165W high stability green laser based on composite ceramic Nd:YAG crystal

A high stability high average-power green laser was reported with composite ceramic Nd:YAG as gain material and KTP crystal as frequency doubler. Average output power of 165 W is obtained at a repetition rate of 25kHz with a diodeto- green optical conversion of 14.68% and measured pulse width of 162 ns. For the average output power of about 160 W, the power fluctuation is less than 0.6%. The experimental results show that the green laser system using this novel ceramic Nd:YAG crystal offers better laser performance and output stability
