Abstract

Optical absorption and emission intensities of the Nd3+ ion in GdAl3(BO3)4 crystal were investigated. Based on the Judd–Ofelt theory, the following spectral parameters were obtained: parameters of oscillator strengths Ωλ,Ω2=1.89×10-20 cm2,Ω4=2.55×10-20 cm2, and Ω6=4.95×10-20 cm2; radiative lifetime, 293 µs; and quantum efficiency 18.7%. The fluorescence branch ratios were calculated: β1=0.341,β2=0.536,β3=0.117, and β4=0.006. The value of stimulated-emission cross section σp was calculated.
