Abstract

With an acousto-optical Q-switch and Co:LaMgAl₁₁O₁₉(Co:LMA) crystal as the saturable absorber, diode-end-pumped actively and passively Q-switched Nd:GdVO₄ lasers at 1.34 μm were demonstrated, respectively. For acousto-optical Q-switched operation, the maximum average output power, the highest pulse energy, the shortest pulse width and the highest peak power were obtained to be 4.54 W, 223 μJ, 19 ns and 11.75 kW, respectively. For passively Q-switched operation with a 0.3-mm-long Co:LMA crystal as the saturable absorber, the maximum average output power, the highest pulse energy, the shortest pulse width and the highest peak power were obtained to be 1.43 W, 112 μJ, 55 ns and 1.95 kW, respectively.
