Amplifying characteristics Er-doped chalcogenide glass

Abstract

The paper presents the measurement results of optical amplifying characteristics of Er-doped As-S-Ge chalcogenide glasses. The measurements included the amplification of useful laser source power during propagation along two axes of samples. A fluorescence maximum at the wavelengths between 1500 and 1540 nm was identified, which corresponds to the transition of electrons from the 4I13/2 level to the 4I15/2 level within the 4f shell of erbium ions (Er3+). Measuring the signal strength showed that the passage through the erbium doped chalcogenid glass amplification of the useful signal occurs and this increase is proportional to the length of propagation through the doped glass.
