摘 要: 采用885 nm激光二极管(laser diode, LD)作为泵浦源,首次实现了885 nm LD直接泵浦Cr,Nd:YAG/KTP腔内倍频自调Q激光脉冲输出。当吸收泵浦光功率为3.1 W时获得了92 mW自调Q绿光脉冲激光输出,对应的光光转换效率为3%,激光输出斜率效率为5.8%. 在实验中获得了脉冲宽度为5 ns、重复频率17 kHz、峰值功率超过1 kW的倍频自调Q激光脉冲输出。随泵浦光功率的增加,Cr,Nd:YAG/KTP腔内倍频自调Q激光器的输出激光脉冲序列呈现周期性交替变化。
关 键 词: 光电子学与激光技术;Cr,Nd:YAG晶体;直接泵浦;腔内倍频;自调Q激光器

Abstract: In this paper, using 885 nm laser diode (LD) as pump source, resonant pumped Cr, Nd:YAG/KTP intracavity frequency doubled self-Q-switched green laser has been demonstrated for the first time. Average output power of 92 mW was obtained at the absorbed pump power of 3.1 W. Corresponding optical-to-optical efficiency of 3% was achieved. Slope efficiency of 5.8% was measured. Laser pulses with pulse width shorter than 5 ns, repetition rate of 17 kHz and peak power over 1 kW were achieved. As the absorbed pump power increases, the laser pulse trains generated in Cr,Nd:YAG/KTP intracavity frequency doubled self-Q-switched lasers exhibit periodical oscillation.
