Аннотация: Absorption spectra of the Nd3+ ions in an orthorhombic δ-BiB3O6 single crystal were measured in the spectral range 11,000-20,500 cm-1. The f-f transition intensities were analyzed in terms of the Judd-Ofelt theory, and the following parameters of the theory were obtained: Ω2 = 6.35 × 10-20 cm2, Ω4 = 4.86 × 10-20 cm 2, and Ω6 = 11.233 × 10-20 cm 2. The strengths, spontaneous emission probabilities, branching ratios, spectroscopic quality factor and excited state radiative lifetime were calculated for laser transitions from the 4F3/2 state to 4IJ manifold. Spectroscopic properties of Nd 3+:δ-BiB3O6 crystal favor lasing at 1.3 μm, where this crystal possesses near non-critical phase matching for second harmonic generation. © 2012 Elsevier B.V.

Аннотация: The polarized absorption spectra of trigonal single crystal Nd0.5Gd0.5Fe3(BO3)4 were measured in the spectral range 10,000–22,000 cm−1. The d–d and f–f transitions spectra were separated. The f–f transitions intensities were analyzed in terms of the Judd–Ofelt theory in a ferroborate with huntite structure for the first time, and the following parameters of the theory were obtained: Ω2 = 4.4 × 10−20 cm2, Ω4 = 8.04 × 10−20 cm2, and Ω6 = 8.25 × 10−20 cm2. The strengths, spontaneous emission probabilities, branching ratios, spectroscopic quality factor and excited state lifetime were calculated for transitions from the 4F3/2 state to 4IJ manifold. All the obtained spectroscopic characteristics were compared with those of alumoborates with the same crystal structure.
