abstract


The description of absorption transition oscillators of holmium ion in yttrium aluminium garnet by three various treatments is carried out: by Judd-Ofelt method, in an approximation of intermediate configuration interaction and by the modified Judd-Ofelt theory. The best description is achieved in the approximation of intermediate configuration interaction, which takes into account the influence of excited configurations on holmium ion multiplets more correctly. The excited configurations with charge transfer essentially influence on low laying 5I6 and 5I7 multiplets and the excited opposite parity configurations strongly influence on highly laying 3H5 &3H6 &5G2 multiplets. The effect of excited configurations on holmium ion multiplets is essential and therefore such important properties for determination of the optimal laser generation channel, as the metastable multiplet lifetimes and branching can correctly be estimated only by the intensity theories which are taking into account the configuration interaction correctly.
