本文报道了Tm：YLF调Q低温振荡器在100W泵浦下，在35ms内输出550mJ、半高宽14ns、重复频率1Hz的脉冲。该激光器有一个共焦非稳谐振腔与梯度反射率输出耦合器，导致在M（2）= 1.5的光束质量。脉冲能量为416和343毫焦耳，分别在10和20赫兹的重复率。
We report 550 mJ pulses with 14 ns FWHM duration at 1 Hz repetition rate from a Q-switched cryogenic Ho:YLF oscillator pumped with 100 W in 35 ms by a Tm:fiber laser. The laser has a confocal unstable resonator with a graded-reflectance output coupler, resulting in a beam quality of M(2) = 1.5. Pulse energies of 416 and 343 mJ were obtained at 10 and 20 Hz repetition rate, respectively.
