By simultaneously employing the electro-optic (EO) modulator and Cr4+:YAG saturable absorber, a diode-pumped dual-loss-modulated Q-switched and mode-locked (QML) YVO4/NdYVO4/KTP green laser is presented. In comparison with the singly passively QML green laser with Cr4+:YAG, the dual-loss-modulated QML green laser with EO and Cr4+:YAG can generate more stable pulse train with deeper modulation depth, shorter pulse width, greater pulse energy and higher peak power. For the dual-loss-modulated QML green laser, at a pump power of 18 W and a repetition rate of 1 kHz, the pulse width and the pulse energy of the Q-switch envelope as well as the peak power of QML green laser are 42.1 ns, 360 mu J and 382 kW, respectively, corresponding to the pulse width compression 62%, the pulse energy improvement 10 times and the QML peak power increase 40 times when compared with that of the singly passively QML green laser.
