Abstract

The methods to control the pulse width of a laser-diode end-pumped doubly Q-switched Nd:YVO4/YVO4 composite crystal laser with acoustic-optic (AO) and GaAs saturable absorber has been theoretically and experimentally studied. By varying the laser beam radius in the Q-switchers and the pump beam radius in the gain medium, we provide efficient means to control the pulse duration. The coupled rate equations are used to analyze the process of the laser. The experimental results are consistent with the theoretical results.
