Abstract
We first report a tunable repetition frequency passively Q-switched 2053 nm Tm,Ho:YLF laser by tuning the tilt angle of the Cr:ZnS saturable absorber. When the pump power is 1.4 W, the pulse repetition frequency can be tuned from 1.6 to 19.4 kHz by changing the position of Cr2+:ZnS saturable absorber along the cavity axis. When the Cr2+:ZnS saturable absorber is near the Tm,Ho:YLF crystal, the repetition frequency can be tuned from 0.8 to 4.0 kHz by changing the tilt angle of the Cr2+:ZnS saturable absorber, furthermore, the pulse width and the pulse energy are near constants of 1.7 μs and 3.5 μJ, respectively.
