Crystal-Field Studies of Excited States of Trivalent Neodymium in Yttrium Gallium Garnet and Yttrium Aluminum Garnet

Abstract

An analysis has been made of the position of Stark components of excited states of the trivalent neodymium ion in the aluminum garnet and gallium garnet host lattices. The crystal-field calculations reveal that not all crystal-field parameters for these states are equal. It has been found that for some states this change cannot be attributed to intermediate coupling effects or J mixing.
