Abstract

The transmission window of the acousto-optic modulator was discussed theoretically. By injecting pulsed higher acoustic power, the FW}{M of the transmission window of the modulator was reduced, so the mode-locked pulse width was reduced to 55ps. In addition, through discharging the λ/4 voltage of the Pockels Cell, a single pulse was dumped out from the intracavity of the laser: the energy was 2mj, the energy variation was ±4%. Besides, the repetition rate of the laser was improved to 30Hz due to the reduction of the laser threshold. It is evinced that this kind of laser has potential for a wide variety of application.
