Abstract: The spectra and spectral parameters of calcium aluminophosphate glass dopedwith Nd3+ions were studied. The absorption, excitation and emission spectra have beenmeasured at room temperature. By using Judd-Ofelt theory the oscillator strengths,Ωλpa-rameter, radiative transition probability, radiative lifetimes and fluorescent branching ratioof Nd3+ ions have been calculated.

Key words: calcium aluminophosphate glass Nd3+ doped, spectral parameter, Judd-Ofelt theory
