Abstract
A diode pumped Nd:Y0.5Lu0.5VO4 pulse laser modulated with an acousto-optic (AO) Q-switcher and Cr4+:YAG saturable absorber is first demonstrated in this paper. The laser is shown to generate shorter pulse width than AO Q-switched laser alone, and have a higher peak power and single pulse energy than passively Q-switched laser with only Cr4+:YAG. A laser pulse width of 6.16 ns and a peak power of about 43.83 kW are achieved at the incident pumping power of 14.09 W.
