Laser parameters of Er+3 doped phosphate glassAuthor(s): P.Kothari
Tripositive Erbium ion doped phosphate glass has been prepared by meltquenching technique. The experimental oscillator strengthswere calculated from the areas under the absorption bands. Judd-Ofelt parameters (ïë) evaluated using the observed spectral intensities have been used to compute various laser parameters viz., spontaneous emission probability (A), radiative life time (ï´), fluorescence branching ratio (ï¢) and stimulated emission crosssection (ï³p). The bonding environment surrounding the rare earth (RE) ion has also been discussed.
