Abstract

Polarized excited state absorption spectra of Er, Yb:YAB are reported. The Stark levels of the 4I15/2, 4I13/2, and 4I11/2 multiplets of Er3+ have been derived from the measured low-temperature absorption and fluorescence spectra. The stimulated emission spectra have been calculated using the reciprocity method, and the radiative lifetime of the erbium 4I13/2 level has been determined indicating high nonradiative decay rates. The thermal conductivity of Er-Yb-codoped YAB crystals has been measured.
