Abstract

The recent years observed significant interest in the development of light sources operating in mid-infrared (MIR) spectral range (> 2.5 μm). This results from their potential applications in atmospheric pollution monitoring, quality control of the production processes (e.g. drugs manufacturing in the pharmaceutical industry), biochemical sensors for detection of explosives, free-space communication, medical diagnostics and may others. The chalcogenide glasses doped with rare earth ions are continuously considered as one of the most promising candidates for optically active material dedicated to operation in MIR spectral range. This is mainly due to very low phonon energies (< 350 cm-1) and high refractive indices, resulting in increased values of absorption and emission cross sections. Mastering the technology of fiber drawing offers possibility of designing and development the MIR fiber lasers, with all the advantages they can guarantee i.e. easiness of obtaining a single mode operation, high gain and excellent thermal properties combined with compact size of the whole device. In this work we present the results of our recent studies on MIR luminescence of dysprosium doped GeAsGaSe glass, with specific attention on analysis of infra-red transitions offered by Dy3+ ions’ energy level structure as well as the main excitation and de-excitation pathways.
