英文摘要:
Single crystal of Ho3+/Yb3+ co-doped PbF2 has been grown successfully by the conventional technique modified Bridgman method. The spectral parameters of HO3+ were calculated based on the Judd-Ofelt theory. The transition probabilities, radiative lifetime, and branching ratios were also estimated in detail by the J-O parameters obtained. The 2 mu m emission characteristic and fluorescence lifetime of the I-5(7), manifold upon excitation of a conventional 970 nm laser diode were measured and investigated. Fuchtbauer-Ladenburg theory was applied to calculate the absorption, emission, and gain cross sections of I-5(7) -> I-5(8) transition. Based on examination of spectroscopic parameters evaluated, we suggest Ho3+/Yb3+ co-doped PbF2 crystal is a promising candidate for efficient 2 mu m laser. (C) 2017 Elsevier B.V.
