A diode-pumped passively Q-switched 1066 nm laser with Nd:GGG crystal was demonstrated. The maximum output power was 4.5 W under the absorbed pump power of 12.56 W, with a slope efficiency of 40% in the continuous-wave (CW) operation. The characteristics of the passively Q-switched Nd:GGG laser with the Cr4+:YAG saturable absorbers were researched. When the Cr4+:YAG crystal with the initial transmission (T0) of 85% at 1.06 µm was placed in the cavity, the maximum repetition rate and the minimum pulse width were 6.7 kHz and 28.7 ns, respectively..
