LiF: F 2 - crystal is used as Q-switched crystal in a pulsed adjustable laser system to realize passively Q-switched dynamic laser output. The output laser waveform is a series of sub-pulses, the width of the sub-pulses is nanoscale, the repetition frequency is 3.3kHz, and the average power is relatively high. In this paper, the characteristics of experimental law are analyzed. Combined with the metastable energy level characteristic of LiF: F 2 - crystal, the reason why the long pulse width laser can output pulse train is explained.
