摘要：

The spectroscopic characteristics of translucent oxysulfide optical ceramics doped by Nd3+, which can be perspective for 1-mu m lasing with high quantum efficiency is considered. Analysis of multiphonon relaxation (MR) rate of the low I-4(11/2) laser level in the ceramics is provided using nonlinear theory of MR for multifrequency model of lattice vibration. MR rate dependence for the transitions with equal number of phonons p = 4 on the extent of the phonon spectrum and Nd3+ to the nearest ligands distance R-0 is established experimentally and analyzed. For the initial F-4(3/2) laser level in the Gd2O2S:Nd3+ and La2O2S:Nd3+ ceramic samples an analysis of the energy transfer kinetics is provided. Different stages of energy transfer-direct energy transfer and a stationary migration-controlled stage are observed and analyzed. Dipole-dipole mechanism of energy transfer is established and microparameters of energy transfer and migration are determined. (c) 2006 Elsevier B.V. All rights reserved.
