摘要/Abstract

摘要： 用连续的钛宝石激光泵浦１ｍｍ厚的Ｃｒ^４＋，Ｎｄ^３＋：ＹＡＧ晶体微片获得了１．０６４μｍ的自调Ｑ激光输出．输出的激光调Ｑ脉冲非常稳定，泵浦的阈值功率为３０ｍＷ，脉冲宽度为１００ｎｓ，随着泵浦功率的变化，脉冲宽度保持不变，而重复率则在变化．斜率效率随着输出耦合镜透过率的变化而变化。当输出耦合率为５％时，斜率效率高达２０％．这一研究有助于进一步发展激光二极管泵浦的全固化的自调Ｑ微片激光器．

Abstract: Using a Ti:sapphire laser as the pumping source in the CW mode, the self-Q-switched laser in the co-doped Cr⁴⁺,Nd³⁺:YAG microchip
with 1mm thickness was demonstrated. The output Q-switched traces are very stable, the threshold pumping power is as low as 30 mW, the pulse duration is as short as 100 ns. And the pulse
width keeps constant and pulse repetition rate is varied with the variation of the pumping power. The slope efficiency is varied with the
transmission of output coupler at 1064nm, and the slope efficiency is as high as 20% for 5% transmission of output coupler at 1064nm. This
can lead to develop the diode laser pumped monolithic self-Q-switched solid-state microchip lasers.
