In Moscow, new laser to treat eye diseases

Scientists at the Moscow Lomonosov State University (MSU) in partnership with colleagues from the Belarus National Technical University in neighboring Belarus have come up with what they claim is a unique laser to treat eye diseases, portal Hi-tech.mail.ru  reported . 

It is reportedly built on specially grown crystals and emits certain wavelength to ensure safety for patients. According to Prof. Nikolay Leonyuk from MSU’s crystallography and crystallochemistry chair, lasers based on yttrium-gadolinium borate crystals reveal record-high thermal conductivity, impressive strength and thermal stability as they only disintegrate at temperatures above 1,280 degrees Celsius. 

The new lasers are expected to serve for 100,000 hours. No vibration has been found in operation, and no water cooling is required. 

In addition, the MSU-originating lasers have linear emission polarization, so it is easy enough to choose parameters required to make sure the system is safe for patients. Last but not the least, the lasers are less costly to produce than the competition, the developers said. 

This unique laser with semiconductor pumping may be used in areas far beyond ophthalmology and medicine in general. The developers expect to apply them to scientific research, developing new telecom solutions, and some other areas.
