It is shown that looking for quasi-spheres allows one to describe the complex spectra of an Er3+-doped silicate glass near 1500 nm in a simple way. It is shown that 'ascending' the symmetry from the generally accepted point symmetry C2V to the pure icosahedral symmetry, brings practical simplification. Looking for a spherical approximation in the crystal field parameter space, brings further simplification through use of the Nv scalar crystal field parameter describing the maximum crystal field splitting of a given J-state. The [image omitted] and [image omitted] icosahedral crystal field values are deduced from it. Such effective ascending symmetry may be of practical importance knowing that the considered 4I13/2 ↔ 4I15/2 transition of Er3+ in silica glasses rules the universally adopted optical amplification in glass fibre telecommunication networks. |
