介绍了一种室温条件下新型高重频2 μm Ho: GdVO4固体激光器。首先在室温条件下利用分光光度计对Ho:GdVO4晶体的吸收光谱进行了测定,通过经典J-O理论计算得到了Ho: GdVO4晶体在2 μm附近的吸收截面；其次通过对荧光光谱的测定与计算,得到了2 μm附近的发射截面；最后通过吸收光谱信息确定了泵浦源波长,利用1 942 nm Tm光纤激光器作为泵浦源实现了在重复频率为30 kHz时平均功率为11 W的激光输出。

A new 2 μm high repetition frequency Ho:GdVO4 solid state laser operating in room temperature conditions is introduced. Firstly, the absorption spectrum of the Ho:GdVO4 crystal is measured with a spectrophotometer in room temperature, and the absorption cross-section of Ho:GdVO4 crystal at 2 μm is obtained by J-O theory. Secondly, through measuring and calculating, the fluorescent spectrum, the emission cross-section at 2 μm is got. Finally, the wavelength of pump source is defined based on the absorption spectrum, the maximum average output power of 11 W is obtained at 30 kHz pumped by a 1 942 nm Tm-fiber laser.
