在935 nm二极管泵浦下，获得了1035 nm、重复频率为26.3kHz、平均输出功率为3.21W的被动调Q小型Yb：Lu 3Ga 5 O 12晶体激光器，光光效率为36.5%，斜率效率为60%。在增大输出耦合度和降低可饱和吸收体的初始透过率的条件下，在8.3kHz频率下获得了1.61W的1026 nm激光输出，脉冲能量、脉宽和峰值功率分别为194 μJ、2.5ns和77.6kW。
A passively Q-switched miniature Yb:Lu3Ga5O12crystal laser is demonstrated under 935-nm diode pumping, producing an average output power of 3.21 W at 1035 nm at a pulse repetition frequency of 26.3 kHz, with optical-to-optical and slope efficiencies being 36.5% and 60%, respectively. With the output coupling being increased and the initial transmission of the saturable absorber being lowered, an output power of 1.61 W at 1026 nm is generated at 8.3 kHz, the resulting pulse energy, duration and peak power were respectively 194 μJ, 2.5 ns and 77.6 kW.
