  ABSTRACT: The absorption and fluorescence spectra of Er3+:LiGdF4 crystal was measured at room temperature. Base on the Judd-Ofelt theory, the intensity parameters of Er3+ in LiGdF4 crystal were determined, Ω2=0.905×10-20cm2, Ω4=2.47×10-20cm2 and Ω6=4.92×10-20cm2. The values of the radiative transition probabilities, branching ratios, integrated emission cross-section and radiative lifetimes of excited states of Er3+ in LiGdF4 crystal were calculated. The stimulated emission cross-section was also evaluated for the 4I13/2→4I15/2 transitions. In comparisons with other Er3+ doped laser crystals, Er3+:LiGdF4 crystal has potential as a promising laser crystal.
