Abstract

By using LD as a pumpingsource, the self-Q-switched laser of Cr,Nd:YAG crystal is demonstrated. The output Q-switched traces are verystable. The threshold pumping power is 3.5 W and pulse duration is 50 ns. The slopeefficiency is as high as 20%. When the input power is 10.8 W, 1.46 W self-Q-switched laserat 1064 nm is obtained. The pulse width keeps nearly constant and pulse repetition ratevaries with the variation of the pumping power.
