首次在准连续激光二极管泵浦下，研究了粘结Yb：YAG晶体增强的Cr，Yb：YAG自调Q微片激光器。研究了准连续激光二极管的泵浦脉冲宽度和泵浦功率对Yb：YAG/Cr，Yb：YAG微片激光器性能的影响。自调Q激光器的光学效率、脉冲能量和峰值功率随抽运脉冲宽度和抽运功率的增大而增大，当抽运脉冲宽度大于1ms时趋于恒定，与Yb：YAG晶体的荧光寿命相当。当输入泵浦能量为48.2nmJ时，获得了11.7mJ以上的输出能量，相应的光-光转换效率为24.3%。获得了脉冲能量为31μJ、峰值功率为13.3kW的激光脉冲。在可用泵浦能量范围内，1030 nm附近的多纵模振荡占主导地位。
Enhanced Cr,Yb:YAG self-Q-switched microchip lasers by bonding Yb:YAG crystal have been studied under quasi-continuous-wave (QCW) laser-diode pumping for the first time to our best knowledge. The effects of the pump pulse duration and pump power of the QCW laser-diode on the performance of Yb:YAG/Cr,Yb:YAG microchip lasers have been investigated. The optical efficiency, pulse energy and peak power of the Yb:YAG/Cr,Yb:YAG self-Q-switched laser increase with the pump pulse duration and pump power, and tend to be constant when the pump pulse duration is longer than 1 ms, which is comparable to the fluorescence lifetime of Yb:YAG crystal. Output energy of over 11.7 mJ was obtained at input pump energy of 48.2 mJ; corresponding optical-to-optical efficiency of 24.3% was obtained. Laser pulses with pulse energy of 31 μJ and peak power of 13.3 kW were obtained. The multi-longitudinal modes oscillation around 1030 nm was dominant within the available input pump energy.
