The spectral and kinetic properties of yttrium-aluminium garnet crystals co-doped with Er{sup 3+} and Yb{sup 3+} are studied in the range from room temperature to 800 {sup 0}C. It is found that the lifetime of the {sup 4}I{sub 11/2} level of the erbium ion decreases approximately by a factor of twenty with increasing temperature and the efficiency of nonradiative energy transfer from Yb{sup 3+} to Er{sup 3+} increases considerably. Analytic expressions describing the spectral and temperature dependences of the absorption and emission cross sections for the transition between the {sup 4}I{sub 13/2} and {sup 4}I{sub 15/2} levels of the erbium ion are proposed.
