Title
Diode-Pumped Passively Q-Switched 
Laser at 1330 nm With  and passively Q-switched Nd:(Lu<sub>0.1</sub>Gd<sub>0.9</sub>)<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> (Nd:LGGG) laser at 1330 nm were realized for the first time. The maximum CW output power of 0.93 W was obtained under the absorbed pump power of 11 W, corresponding to the slope efficiency of 10.4. By using V<sup>3+</sup>:YAG crystal as an absorber for passively Q-switching operation, the maximum average output power of 167 mW was generated with the minimum pulsewidth of 15.6 ns and the maximum repetition rate of 10 kHz. The corresponding signal pulse energy and pulse peak power were calculated to be 16.7 μJ and 1.1 kW, respectively.</div></div>
