Temperature dependence of the 1.03 μm stimulated emission cross section of Cr:Yb:YAG crystal

The fluorescence emission spectra of Cr:Yb:YAG crystal are measured and the effective stimulated emission cross section of the crystal are obtained from −80 °C to +80 °C. A linear temperature dependence between −80 °C and +80 °C is reported for the 1.03 μm peak stimulated emission cross section of Cr:Yb:YAG crystal.
