Spectroscopic and optical properties of the rare earth doped liquid PBr3/AlBr3/SbBr3
A complete spectroscopic evaluation of rare earth-doped PBr3/AlBr3/SbBr3 has been carried out for several of the lanthanides. A comprehensive assignment of 4f energy levels has been made and absorption and fluorescence spectra have been used in evaluating the Judd-Ofelt parameters for most of the rare earths studied. The stimulated emission cross sections for the 4F(3/2) - 4 I (11/2) transition in the neodymium-doped solution was found to be sigmaNd = 6.8 x 10-20 cm2, and for the 4 I (13/2) - 4 I (15/2) transition in the erbium-doped solution sigmaEr = 6.2 x 10-21 cm2. Non-radiative relaxation rates and stimulated emission cross sections have also been evaluated for potential laser transitions in the 3-5 µm spectral region

Abstract

A complete spectroscopic evaluation of rare earth-doped PBr3/AlBr3/SbBr3 has been carried out for several of the lanthanides. A comprehensive assignment of 4f energy levels has been made and absorption and fluorescence spectra have been used in evaluating the Judd-Ofelt parameters for most of the rare earths studied. The stimulated emission cross sections for the 4F(3/2) - 4 I (11/2) transition in the neodymium-doped solution was found to be sigmaNd = 6.8 x 10-20 cm2, and for the 4 I (13/2) - 4 I (15/2) transition in the erbium-doped solution sigmaEr = 6.2 x 10-21 cm2. Non-radiative relaxation rates and stimulated emission cross sections have also been evaluated for potential laser transitions in the 3-5 µm spectral region
