The crystal field energy levels of laser crystal Gd3Ga5O12:Nd3+ are calculated using the diagonalization (of energy matrix) method. From the calculations, the 93 observed crystal field energy levels are explained reasonably and the root-mean-square (r.m.s.) deviation sigma(approximate to 25.6 cm(-1)) and the scalar crystal-field strength parameter Nv (approximate to 3847 cm(-1)) are obtained. The results are discussed. (C) 2011 Elsevier GmbH. All rights reserved.
