Temperature dependence of the 1.064-μm stimulated emission cross-section of Cr:Nd:YAG crystal

The fluorescence emission spectra of Cr:Nd:YAG crystal are measured and the effective stimulated emission cross-section of the crystal is obtained from −80 to +80 °C. A linear temperature dependence between −80 and +80 °C is reported for the 1.064-μm peak stimulated emission cross-section of Cr:Nd:YAG crystal.
