title: [Calculation and analysis of optical transitions of Pr3+ ions in fluoride glass].
abstract: Intensity parameters of Pr3+ in ZBLAN glass were calculated using Judd-Ofelt(J-O) theory with absorption spectrum measurement. The anomalous behavior of Pr3+ was discussed using J-O theory. Base on the intensity parameters, the optical parameters such as spontaneous emission rate, branching ratio, and integrated emission cross section etc were predicted. The future of the glass as a laser material was discussed, and the probability of photon avalanche in the material was also analysed.
