Abstract
This paper reports a study of absorption, luminescence and excitation spectra of single- and double-doped Ce3+,Yb3+:SrAlF5 (0.5Â at%.) single crystals. Spectral properties of different types of impurity centers of Ce3+, Yb3+ and Yb2+ ions are described. Experimental energy level diagrams for optically nonequivalent Ce3+, Yb2+ and Yb3+ centers in double-doped Ce3+, Yb3+: SrAlF5 single crystals are suggested. Lasing on Ce:SAF single crystal at 290Â nm under 248Â nm pumping was demonstrated for the first time.
