Abstract：In the present paper the authors firstly measured the absorption spectra of Er3+ in the sample Er3+∶YVO4 (0.5%), then calculated the intensity parameters are calculated by using the Judd—Ofelt theory. After that the authors dealed with some predicted spectroscopic parameters, such as the oscillator strength, spontaneous radiative transition rate, branching ratio and integrated emission cross section. And Er∶YVO4 crystal application value has been analyzed with the optical parameters. Especially there are large oscillator strengths and large integrated emission cross sections in the transitions of 4I13/2→4I15/2, 2H11/2→4I15/2, 4S3/2→4I15/2, and4F9/2→4I15/2. So, they are more worth of attention. Moreover, by comparing the Er-doped yttrium vanadate crystal and other Er-doped crystal optical properties, the authors can see the advantages of YVO4 as laser crystal. Finally, the authors discussed the splitting of the energy levels of Er3+ in the crystal YVO4 based on the group theory.
