Abstract

A diode-pumped dual-loss-modulated Q-switched and mode-locked (QML) Nd : Gd VO 4 / KTP green laser with an acousto-optic modulator (AOM) and GaAs saturable absorber is presented. The experimental results show that the stability and the peak power of the dual-loss-modulated QML Nd : Gd VO 4 / KTP green laser are significantly improved. The pulse width of the Q-switched pulse envelope in the dual-loss-modulation QML green laser has a compression of 50% compared with that in the singly passively QML green laser with GaAs. By using a hyperbolic secant square function and considering the Gaussian distribution of the intracavity photon density, the coupled equations for diode-pumped dual-loss-modulated QML Nd : Gd VO 4 green laser are given, and the numerical solutions of the equations are in good agreement with the experimental results.
