摘　　要：展示了一种环形腔全固态单纵模被动调Q激光器。采用激光二极管(LD)侧面泵浦的环形腔消除空间烧孔效应,实现谐振腔内纵模数量的稳定;通过标准具控制激光器相邻纵模间的净增益差,实现高单纵模率激光输出。激光器以10 Hz的重复频率运行,脉宽为23.6 ns,单脉冲能量为6.1 mJ。该激光器在输出能量以及单纵模率方面具有较好的稳定性,其相对标准差为1.56%,当连续记录一万发脉冲时,单纵模率为100%。An all-solid-state single-longitudinal-mode passively Q-switched laser in a ring cavity is demonstrated.The laser diode(LD)side-pumped ring cavity is adopted to eliminate the spatial hole burning effect to stabilize the number of longitudinal modes in the resonator,and the etalon is used to control the net gain difference between adjacent longitudinal modes of the laser to realize the operation of a high single-longitudinal-mode ratio laser.The laser operates at a repetition rate of 10 Hz,producing pulses with a pulse width of 23.6 ns and a pulse energy of 6.1 mJ.The laser has strong stability in output energy and single-longitudinal-mode ratio,a relative standard deviation of 1.56%is demonstrated,and a singlelongitudinal-mode ratio of 100%is achieved when 10000 pulses are recorded continuously.
