Multi-component titanium-germanate glassn

Scientists associated with the Faculty of Science and Technology of the University of Silesia designed new multi-component titanium-germanate glass that can be used in laser technology. These are vitreous materials for near infrared laser applications. The solution is covered by patent protection.

Glass for the production of optical fibres

The new oxide-fluoride titanium-germanate glass was designed by scientists associated with three universities: University of Silesia, AGH University of Science and Technology, and Bialystok University Of Technology. These transparent materials with a pink tint emit intense radiation in the mid-infrared range. Thanks to this, they can be used as a building block of broadband optical amplifiers, which are an important element of modern fibre optic networks.

Ceramic materials for laser applications

Germanate ceramic phosphors – this is the name of materials designed by a team of scientists from the University of Silesia. These materials show very promising optical properties, and as such they are considered as solutions used in laser technology. Their advantage is a fairly easy production method, thanks to which it is possible to obtain materials with a higher concentration of optically active compounds. What is more, they are obtained in a much shorter time than in the case of, for example, currently used laser single crystals. The solution is covered by patent protection.
