It is shown that, as the temperature of an Yb, Er:YAG crystal is increased from room temperature to 400-600{sup 0}C, the efficiency of energy accumulation on the {sup 4}I{sub 13/2} level of the Er{sup 3+} ion increases by several times upon optical pumping through Yb{sup 3+} ions. Under these conditions, up to 60% of erbium ions can be excited, which gives promise that lasing at a wavelength of 1.54 {mu}m can be achieved in the Yb, Er:YAG crystal in the three-level scheme.
