Abstract

A diode-pumped GaAs-passively-Q-switched intracavity-frequency-doubled Nd:YVO₄/YVO₄ green laser with a MgO-PPLN is presented. The characteristics of the passively Q-switched green laser pulses have been investigated. At the maximum incident pump power of 5.19 W, the minimum green-light pulse width of 26.4 ns has been obtained at a repetition rate of 134 kHz. The rate equations are presented to simulate the process of the green laser, and the numerical solutions of the coupled rate equations accord with the experimental results.
