Abstract
This paper reports the spectral characteristic of Cr3+-doped La0.83Y0.29 Sc2.88 (BO3)4 crystal. Cr3+-doped La0.83Y0.29Sc2.88 (BO3)4 crystal was grown from a flux of Li6B4O9 by the top seeded solution growth method. Cr3+:La0.83Y0.29 Sc2.88 (BO3)4 crystal exhibits broad absorption and emission bands of Cr3+ ions. The absorption cross-section Ïa is 3.38 Ã 10â20 cm2 at 467 nm and 4.40 Ã 10â20 cm2 at 656 nm for E//c, respectively. The emission band with a peak at 906 nm has a full width at half maximum (FWHM) of 188 nm for E//c. The emission cross-section Ïe at 906 nm is 2.35 Ã 10â20 cm2 for E//c axis and 2.03 Ã 10â20 cm2 for Eâ¥c axis. The fluorescence lifetime of 4T2 â 4A2 transition is 37.7 μs. The investigated result indicates that it may be considered as a potential CW tunable laser crystal material.
