Abstract
LaGaO3 crystals doped with Er3+ ions were grown by the Czochralski method a nd their optical properties were examined. The Er3+ energy levels have been determined from the low-temperature absorption and emission spectra. The r esults of Judd-Ofelt analysis are presented and compared with experimental data. The emission cross sections are determined for the I-4(13/2) --> I-4( 15/2) (1.55 mu m) and I-4(11/2) --> I-4(13/2) (2.85 mu m) transitions of er bium.
