Title: Spectrometric analysis of different fluorophosphate glasses doped with Sm{sup 3+} ions for reddish-orange laser emission

Optical properties of Sm{sup 3+} doped different fluorophosphate glasses have been synthesized and discussed. The J- O intensity parameters Ω{sub λ} (λ= 2, 4, 6) from absorption spectra have been evaluated. No sharp edges are found in the absorption spectra, which confirm amorphous nature of present glass matrices. Various radiative parameters have been obtained from luminescence spectra for excited states to corresponding {sup 4}G{sub 5/2}→{sup 6}H{sub 5/2}, {sup 6}H{sub 7/2}, {sup 6}H{sub 9/2} and {sup 6}H{sub 11/2} transitions. The nature of decay curve analysis was performed for the {sup 4}G{sub 5/2} level. These glasses are expected to give interesting application in field of optical devices.
