<title>Optical characterization of infrared glasses and waveguides for power delivery and biomedical sensor systems</title>

Abstract

The preparation puxe glasses, fiber's drawing and optical characterization of chalcogenide (As2S3, As4Se3) and chalcolialide (As-Se-(Br,I), Ge-Se-I, Te-Se-Br etc) are given. Their transfer properties are suitable for a laser delivery of Er:YAG. CO and CO2 laser energy. For active optical fibers sulfide GeGaS and GeGaAsS glasses doped with Pr3 ions were prepared and their optical and fluorescence properties are studied and offer perspection applications as the spectral fluorescence. the fluorescence lifetimes G4 and the temporal fluorescence decay in a biomedical sensors.
