Paper Abstract

A passively Q-switched pulse-LDA (laser diode array)-pumped Nd:YVO4 laser using As+ implanted GaAs as the saturable absorber is demonstrated. In the experiment, a Q-switching pulse width 7ns with a pulse energy 23.5μJ is achieved which, to our knowledge, is the shortest pulse width in a passively Q-switched Nd:YVO4 laser using GaAs as saturable absorber. The laser emits only one Q-switching pulse during each pump-pulse time with a Q-switching efficiency of 26.8%. We also investigate the characteristics of the Q-switched pulse by adjusting the pumping pulse energy, pulse width and pulse repetition rate respectively. The experimental results are discussed as well in the paper.
