Light luminescence quenching in Nd-doped crystals: the method for nonradiative relaxation rate measurements

Nonradiative relaxation from the 4G7/2 level of Nd3+ in YAG was investigated by the luminescence light quenching method. This method is described in detail. Luminescence quenching from the 4F3/2 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 4G7/2 level in YAG was estimated to be about 109 sec-1.
