Growth and polarized spectral properties of Sm3+ doped in Ca3La2(BO3)4 crystal
Source abstract
Abstract
Abstract A Sm3+-doped Ca3La2(BO3)4 single crystal was grown by the Czochralski method. Its polarized absorption, emission spectra and fluorescence lifetime measurements were carried out at room temperature. Based on the Judd–Ofelt theory, the spectroscopic parameters Ωt (t = 2, 4, 6), radiative transition probabilities, radiative lifetime and fluorescence branching ratios were obtained. The stimulated emission cross section, the fluorescence lifetime and the quantum efficiency of the promising laser transition were also calculated and compared with other reported crystals. The results showed that Sm3+:Ca3La2(BO3)4 is a promising candidate for the orange–yellow laser emission.
