✦ Synopsis

A diode-pumped dual-loss-modulated Q-switched and mode-locked (QML) Nd:GdVO4 laser with acousto-optic (AO) modulator and Cr 4+ :YAG saturable absorber is presented. The experimental results show that the dual-loss-modulated QML laser has the nearly 100% modulation depth and deeper than the modulation depth 85% of the passively QML pulse. The Q-switch pulse energy of the dual-loss-modulated QML laser are measured and higher than that only with Cr 4+ :YAG. The stability of the QML laser with the dual-loss-modulation is significantly improved if compared to that only with Cr 4+ :YAG.

Regular and robust Q-switched and mode-locked (QML) pulses are produced in Nd:GdVO~4~ laser by the integration of nonlinear mirror and semiconductor saturable absorber mirror. The threshold of QML operation is increased by putting the SESAM in laser cavity with large beam radius. The nonlinear mirro
