Abstract

Nonradiative relaxation from the ⁴G_7/2 level of Nd³⁺ in YAG was investigated by the luminescence light quenching method. This method is described in detail. Luminescence quenching from the ⁴F_3/2 level is a result of stimulated emission under simultaneous 532 and 1064 nm pulse excitation. The experimental data is compared with theoretical data. The relaxation rate from ⁴G_7/2 level in YAG was estimated to be about 10⁹ sec^-1.
