Résumé en anglais

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 cm2, and Ω6 = 11.233 × 10−20 cm2. 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. Spectroscopicproperties of Nd3+:δ-BiB3O6crystal favor lasing at 1.3 μm, where this crystal possesses near non-critical phase matching for second harmonic generation.< Réduire
