Abstract

We develop a theoretical model of multimode rate equation that accurately describes mode evolution mechanism of prelase Q-switched Pr3+:YLF single longitudinal mode (SLM).The theoretical simulation process explained each part of the operation and experimental phenomenon in the pre-lase process effectively.We identify that there is an optimal parameter for the two step signal of acoustic-optic modulator which determines the stability of SLM output.Our theoretical model can be applied to most solid-state lasers, and offer theoretical references for the design and construction of experimental facilities, which is significant for future research.Up to now, there is still not a complete theory to accurate description of prelase Q-switching technology. Moreover, there have been no reported about directly emitting Q-switched SLM laser in the visible region.
