title: Optical properties of Sm3+ doped calibo glass with addition of lead oxide.
abstract: Optical absorption and fluorescence spectra of Sm3+ doped calibo glasses and the effects on these on addition of lead oxide have been recorded. The concentration of lead oxide has been varied from 0 to 30 mol%. The Judd-Ofelt intensity parameters Omegalambda (lambda=2, 4, 6) for f-f transitions in Sm3+ ions trapped in these glasses are calculated and their variation with increase in proportion of lead oxide has been discussed. It is observed from the fluorescence spectra that the intensity of fluorescence reaches a maximum when 20% of PbO is present. Stimulated emission cross-section is calculated and compared with its value for other lattices.
