Abstract
Stable and robust pulses can be generated in a diode-pumpedQ-switched and mode-locked(QML) c-cut Nd:GdVO4/V3 + :YAG laser at 1.34 µm by inserting an acousto-optic modulator (AOM) into the laser cavity.In this kind of dual-loss-modulation QML laser, the pulse width of theQ-switched pulse envelope has a compression of 68% and the pulse energy has animprovement of seven times compared with that in the solely passively QML laser withV3 + :YAG. By considering the influence of the turnoff time and the modulation frequency of theAOM as well as the thermal lens effect, a developed rate equation model fordual-loss-modulation QML lasers is given and the numerical solutions of the rate equationsare in good agreement with the experimental results.
