Popis: | A Sm 3+ -doped LiLuF 4 single crystal was grown by the vertical Bridgman–Stockbarge technique. Polarized absorption spectra, polarized fluorescence spectra, and fluorescence lifetime of the Sm 3+ :LiLuF 4 crystal were recorded at room temperature. Based on the Judd–Ofelt theory, spectral parameters of the Sm 3+ :LiLuF 4 crystal were calculated. Emission cross sections for the 4 G 5/2 → 6 H J ( J = 5/2, 7/2, 9/2, and 11/2) transitions with special interest for visible laser application were obtained by the Fuchtbauer–Ladenburg formula. The results indicate that the Sm 3+ :LiLuF 4 crystal may be a potential laser gain medium operating in visible region pumped by diode lasers around 401 nm. |
