对利用克尔透镜效应实现的自调Q Nd:LuAG激光器进行了数值和实验研究。通过应用6%和1.4%的两个输出耦合器，分别产生193.4 ns和5.1 ns的最短脉冲，而相应的重复率分别为1.175 MHz和96.15 MHz。相对于 3.34 W 和 2.56 W 的平均功率，该系统的光光效率分别为 21.87% 和 21.1%，耦合器分别为 6% 和 1.4%。高重复频率的短脉冲可以在许多领域得到应用，这说明了这种自调Q激光器的研究具有很高的价值。
Numerical and experimental studies were investigated for the self-Q-switching Nd:LuAG laser which was achieved by the Kerr lens effect. By applying two output couplers of 6% and 1.4%, the shortest pulses of 193.4 ns and 5.1 ns were generated respectively while the corresponding repetition rates were 1.175 MHz and 96.15 MHz respectively. Related to the average powers of 3.34 W and 2.56 W, the system demonstrated the optical to optical efficiency of 21.87% and 21.1% for coupler of 6% and 1.4% respectively. The short pulses with the high repetition rates can be applied in many fields which demonstrate the high value of the research on this self-Q-switching laser.
