چکیده انگلیسی
We have demonstrated an efficient diode-pumped passively Q-switched Nd:GdVO4 laser working at 1342Â nm by using an uncoated V3+:YAG crystal as the saturable absorber, in which both a-cut and c-cut Nd:GdVO4 crystals are employed. At the maximum absorbed pump power of 9.45Â W, the maximum average output power can reach 519Â mW and 441Â mW corresponding to the output coupler with different transmission of 3% and 10% by using an a-cut Nd:GdVO4 crystal at 1342Â nm, while the shortest pulse duration could be as low as 21.7Â ns and 22.3Â ns with the repetition rate of 48.41Â kHz and 53.25Â kHz by using a c-cut Nd:GdVO4 crystal, corresponding to the output coupler with different transmission of 3% and 10% at 1342Â nm, and the single Q-switched pulse energy are 6.67Â uJ and 7.06Â uJ, the pulse peak power are 307Â W and 316Â W, respectively. The experimental results show that c-cut Nd:GdVO4 laser can generate shorter pulse with higher peak power in comparison with a-cut one.
