摘要Optical properties of a Ho-doped LaF3 single crystal have been detailed investigated as a promising material for 2 mu m and 2.9 mu m lasers for the first time. Judd-Ofelt theory was applied to analyze the absorption spectrum to determine the J-O intensity parameters Omega(t(t=2,4,6)), based on which the emission probabilities, branching ratio and radiative lifetime for the as-grown crystal were all calculated. The stimulated emission cross-sections of the I-5(7) -> I-5(8) and I-5(6) -> I-5(7) transitions were obtained by using the Fuchtbauer-Ladenburg method. The gain cross-section for 2 mu m emission becomes positive once the population inversion level reaches 30%. The Ho:LaF3 crystal shows long fluorescence lifetime of I-5(7) manifold (25.81 ms) as well as I-5(6) manifold (10.37 ms) compared with other Ho3+-doped crystals. It can be proposed that the Ho:LaF3 crystal may be a promising material for 2 mu m and 2.9 mu m laser applications. (C) 2016 Elsevier B.V. All rights reserved.
