摘要：

For Nd:LaxY1-xVO4 (x = 0.11) crystal, the F-4(3/2) -> I-4(13/2) transition property was investigated for the first time. The fluorescence peak of Nd:La0.11Y0.89VO4 crystal exhibited obvious inhomogeneous broadening comparing with that of Nd:YVO4 crystal. With laser diode array as pump source, 1.34 mu m continuous-wave (CW) and active Q-switched laser operations based on F-4(3/2) -> I-4(13/2) transition were realized. For CW laser operation, the maximum output power of 2.47, 2.13 W is obtained with slope efficiencies of 29.4%, 27.6%, and optical to optical conversion efficiency of 26.2%, 24.7%, respectively for a, c cut crystal samples. For acousto-optic (AO) Q-switched laser operation, the shortest pulse width, highest peak power and maximum pulse energy came from the a-cut sample, which were 13 ns, 2.69 kW and 35 mu l, respectively.
