Abstract: The spectral characteristics of YGG:Cr3+ crystal was investigated experimentally. The absorption spectrum at 300 K and the fluorescence spectrum at 10 K, 133 K, and 300 K are presented. The fluorescence life time, nonradiative transition propability and radiative quantum efficiency as the function of temperature are also presented. Based on the absorption spectrum and the fluorescence spectrum, with the perturbation of C3iS6 low symmetry field, the individual sub-staes resulting from the splitting of Cr3+ 2T1 state in the YGG host, and the location of R line due to 24A2→E zero phonon transition are determined.
