摘要: A spectroscopic study of Y b3+ ions in Al3(BO3)4 laser crystals is presented. Polarized absorption and site selective spectroscopy experiments at low temperature have been used to determine the presence two different centres this host crystal concentration range 0.2–9 at.%. The contribution these spectra has found be dependent on total concentration, Stark energy level diagrams corresponding determined. importance electron–phonon coupling optical transitions also pointed out.
