TOWARDS MIR (MID-INFRARED) FIBER LASING: Extrusion and Fiber-drawing of Composite Material Rod Preforms
Abstract
The overall Aim of this research is to demonstrate MIR (mid-infrared) fiber lasing by fabricating fiber from a composite material comprising: Fe:ZnSe active nano-crystals suspended in a chalcogenide glass host. The active fibers are nano-glass-ceramics. Experiments to date, show that the Fe:ZnSe nano-crystals tend to dissolve during glass melting. So the desired composite material of Fe:ZnSe active nano-crystals suspended in a chalcogenide glass host is not produced. To overcome this problem, the proposed Project comprises two new, parallel synthetic approaches of: (i) core-shell and (ii) extrusion. (i) The first synthetic approach of ‘core-shell’ is to deposit a protective shell around the Fe:ZnSe nanocrystals to prevent their dissolution during glass melting to make a composite rod at UCF. The composite material rod will be drawn to nano-glass-ceramic fiber at UoN. (ii) The second synthetic route is different. The Fe:ZnSe nano-crystals and glass powdered precursors will be extruded to make a composite material rod at UoN. The composite material rod will be drawn to nano-glass-ceramic fiber at UoN.
