摘要
The reason for the instability of passively Q-snitched lasers has been analyzed. Based on those reasons a novel model named pre-pumping passively Q switching is presented. The model we developed accounts for the properties of the lasing material, the saturable absorber, the pumping power and the resonator. With the aid of new factor f(p), we calculate the effects of pre-pumping mechanism on the pulse output energy. Like the model of Guohua Xiao the express we derived can be used to optimize the laser's performance.
