A TSU laser can help pilots land aircraft in bad weather

The staff of the TSU Faculty of Innovative Technologies with colleagues from the Pulslight Ltd company (Bulgaria) have invented a multi-wavelength laser MLM-01, which works on the metal vapor of copper, strontium, calcium, and barium. The new system can be used in various areas, for example, to provide reliable navigation of planes and ships in low visibility conditions.

- Functional characteristics of the laser are determined by its active medium. It affects the range of wavelengths at which the installation can work, - says Aleksey Shumeyko, one of the main developers, head of the Educational Laboratory of Laser Systems at the Faculty of Innovative Technologies. - For example, the use of copper bromide provides radiation in the yellow-green region of the spectrum. It can be used in laser microscopes and in luminance amplifiers, and also for the treatment of skin disorders in dermatology.

If we take calcium as the active medium, the installation will operate at a frequency of 5 microns – that is the average area of the IR spectrum of the radiation. Such a laser can be used to break the bonds of complex organic molecules and create genetic modifications in biology and medicine.

In addition, this development by TSU scientists can be utilized in many other areas, in particular for navigating airplanes and ships in low visibility conditions.

- The laser, which uses barium as the working medium, radiates 1.5-3 microns in the invisible range, - explains Aleksey Shumeyko. - Such radiation is easily visible to recording systems, but the beam does not blind pilots.

The multi-wavelength laser MLM-01, along with the Sr-05, another development of the Faculty of Innovative Technologies - the world's only laser system for cutting brittle materials such as silicate glass - were recently presented at the 72nd International Technical Fair “International Technical Fair 2016 Plovdiv”. Both inventions were awarded gold medals by one of Europe's largest exhibition events.
