Laser parameters of Er+3 doped phosphate glass

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 (ë) evaluated using the observed spectral intensities have been used to compute various laser parameters viz., spontaneous emission probability (A), radiative life time (), fluorescence branching ratio () and stimulated emission crosssection (p). The bonding environment surrounding the rare earth (RE) ion has also been discussed.
