Aluminum- Barium- Calcium-Magnesium Fluoride glasses containing Ho3+in (45- x):AlF2:15 BaF2:15 CaF2: 25 MgF2: xHo2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by xray diffraction studies. Optical absorption spectra were recorded at room temperature for all glass samples. The experimental oscillator strengths were calculated from the area under the absorption bands. Slater-Condon parameter (F2), Lande's parameter (ξ4f), Nephlauxetic ratio (β') and Bonding parameter (b½) have been computed. Using these parameters energies and intensities of these bands has been calculated. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross–section of various emission lines have been evaluated.
