Abstract

Dy3+-doped YAlO3 single crystal has been successfully grown by Czochralski technique. The spectroscopic parameters were determined by Judd-Ofelt theory based on the measured polarized absorption spectra. Dy:YAP crystal exhibits a yellow emission centered at 574 nm which can be used for pumping of the forbidden 1S0-3P0 ytterbium clock transition. The decay lifetime of the 4F9/2 level was measured to be 185 μs.
