报道了激光二极管泵浦Yb：YVO_4晶体的生长、光谱特性和激光性能。对于YVO 4中的Yb 3+离子，在985 nm处的峰值吸收截面为7.4 × 10（-20）cm 2，辐射寿命为0.25 ms，在1008 nm处的受激发射截面为1.25 × 10（-20）cm 2。Yb：YVO_4晶体在1020-1027 nm波长范围内获得连续激光输出，输出功率为610 mW，斜率效率为49%。
The growth, spectroscopic properties, and laser performance of Yb:YVO4 crystal with laser diode pumping are reported. A peak absorption cross section of 7.4 x 10(-20) cm2 at 985 nm, a radiative lifetime of 0.25 ms, and a stimulated-emission cross section of 1.25 x 10(-20) cm2 at 1008 nm for pi polarization were determined for the Yb3+ ions in YVO4. Continuous-wave laser action of Yb:YVO4 at 1020-1027 nm was demonstrated with an output power of 610 mW and a slope efficiency of 49%.
