✦ Synopsis

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 mirror absorber can further increase nonlinear loss modulation of pulses to produce the stable and periodic QML pulses.

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 modulatio

An effective supercontinuum (SC) generation is demonstrated by injecting picosecond self Q-switched mode-locked Nd:GdVO~4~ laser pulses into a 1-m long microstructured fiber. The laser is operated at wavelength 100-nm away from the longer zero-dispersion of this dual zero-dispersion wavelength micro
