title: [Optical parameters of Er3+ in oxyfluoride glass ceramic].
abstract: Recently, in virtue of the develop of the semiconductor laser and the doped laser materials with rare-earth ions, the up-conversion laser with resonant pump has became a scientific subject in great demand. The doped oxyfluoride glass ceramic with rare-earth ions is a very excellent material, its optical property and chemical stability are outstanding. So, absorption spectrum of Er3+ in Fluoroxide glass ceramic was measured, and intensity parameters omega lambda were calculated using Judd-Oflet theory. Some predicted spectroscopic parameters of the excited states, like the spontaneous radiative transition rate, branching ratio and integrated emission cross section were given.
