Er3 doped alkaline-free glass systems based on ,MgF2-BaF2-Ba(PO3)2-Al(PO3)3 (MBBA system), was investigated with the aim of using as high gain media The absorption spectra were recorded to obtain the intensity parameters (Ωt) which are found to be Ω2= 4.47×10-20 cm 2, Ω4=1.31×10-20 cm2, Ω6=0.81× 10-20 cm2 for the MBBA system. The emission cross section for the 4I13/2 →4 I15/2 transition is determined by the Fuchtbauer-Ladenburg method and found to be 2.35 ×10-20cm2
for the MBBA systems. Comparison of the measured spectroscopic values to those of
Er3+ transitions in other glass hosts suggests that new MBBA systems are good candidates for broadband compact optical fiber and waveguide amplifier applications.
