Prof. Wojciech Pisarski and Prof. Eng. Joanna Pisarska from the Faculty of Science and Technology are the co-authors of three patented solutions. Two of them will be used in laser technology, the third can be used mainly in the production of optical fibre.

Lasery

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.

Authors of the invention: Prof. Wojciech Pisarski, Prof. Eng. Joanna Pisarska, Marta Kuwik, PhD, Agata Górny, MSc Eng.

Lasery

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.

Authors of the invention: Prof. Wojciech Pisarski, Prof. Eng. Joanna Pisarska, Marcin Kochanowicz, PhD, DSc Eng., Associate Professor of the Bialystok University of Technology, Prof. Dominik Dorosz.

Lasery

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.

Authors of the invention: Prof. Eng. Joanna Pisarska, Ewa Pietrasik, PhD Eng., Marta Kuwik, PhD, Prof. Wojciech Pisarski.
