Paper Abstract

The various processes leading to loss of efficiency and to heating effects in YAG:Nd laser crystals are discussed. It is thus shown that there are several unavoidable intrinsic sources of loss such as the spectral inhomogeneities in the melt grown crystals and the concentration quenching of emission and these impose upper limit quantum efficiency function on the activator concentration. The estimations made within these models are in a good agreement with the data on quantum efficiency of emission or on fractional thermal loading.
