With a specially constructed miniature acousto-optical Q-switch, 2 ns pulses with 10.3 µJ energy and 5.13 kW peak power at 80 kHz repetition rate were obtained in an end pumped short cavity acousto-optically Q-switched Nd:YVO4 laser. This is believed to be the shortest pulse width obtained in a solid-state laser by acousto-optical Q-switching. At 500 kHz repetition rate, 10 ns pulses were generated.
