Paper Abstract

By considering the AO switch as a low speed switch and the AO turnoff time including the transit time of the acousticwave and the electronic turnoff time as well as the Gaussian spatial distribution of the intra-cavity photon density, the coupled equations of a Laser-diode pumped actively Q-switched Nd:YVO4 laser with acoustic-optic modulator are given. By changing the position of AO in the cavity for changing the transit time of the acoustic-wave, the effect of the AO transit time on the characteristics of the output Q-switched pulse is obtained. It is show that the longer transit time leads to the wider pulse duration. In the experiment, a laser-diode-pumped actively Q-switched Nd:YVO4 laser with acoustic-optic modulator is realized, and the experimental results are in fair agreement with the numerical solutions.
