✦ Synopsis
We investigated a high power diode-laser pumped passively Q-switched c-cut Nd:GdVO~4~ solid-state laser, lasing at 1.34 μm, with a Co^2+^:LaMgAl~11~O~19~ saturable absorber. With the optimum output coupler transmission T=5.5% and pump power of 11.5 W, the static output power of 3.01 W was obtained. The passively Q-switching operation with Co:LMA (initial transmission T
~0~=90%) as saturable absorber, shows that the shortest output pulse width, the highest output power, the highest pulse repetition and the highest pulse peak power were 32 ns, 266 mW, 277 kHz, and 187 W, respectively.
