Fiber damage threshold
WebSpecial pure chalcogenide glass is the material of choice for many mid-infrared optical fibers and fiber lasers. In this paper, the thermo-optical lensing and laser-induced damage were studied in Ge35As10S55 and Ge20As22Se58 glasses and compared with the well-studied As2S3 glass. The thermal Z-scan technique with the quasi-CW Tm-doped fiber laser at … WebTreatment with as little as 1 W of laser power increased the damage threshold by more than an order of magnitude. The study, which the researchers reported in the Nov. 20, …
