Abstract: | Transparent Nd: BiB3O6 crystal has been grown by top-seeded method. The refraction indices of the crystal were measured and the parameters of chromatic dispersion were fitted. The room temperature absorption spectra of the crystal have been measured and compared with that of 0.2 mol/L NdCl3 solution. According to Judd-Ofelt (JO) theory, the spectral strength parameters Ω2 = 0.1776×10?20 cm2, Ω4 = 0.1282?10?201 cm2 and Ω6 = 0.1357X10-20 cm2 of Nd3+ ion were fitted. The radiative transition probabilities AJ,J’, oscillator strengths fJ,J’, radiative lifetime rand the branching ratio βJ’ have all been calculated. Based on these parameters, the properties and application perspective are discussed. |
