LD Pumped Cr4+,Nd3+:YAG with Self-Q-switched Laser Output of 1.4 W
摘要
用激光二极管(LD)抽运Cr4+,Nd3+:YAG晶体获得了1.064μm的自调Q激光输出.激光输出模式为稳定的单纵模,抽运阈值功率为3.5W,脉冲宽度为50ns,斜率效率高达20%.当输入的抽运功率为10.8W时,获得了1.46W的自调Q激光输出.随着抽运功率的变化,脉冲宽度基本上保持不变,而重复率则在变化.
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.
