TOMSK, Sept 15 – RIA Tomsk. The
graduate student of Tomsk State University of Control Systems and Radio Electronics (TUSUR) Anton Kotin plans to develop Russian technology of
receiving coverings for lasers optics which isn't conceding to foreign analogs
according to the characteristics by 2018.
"There are no such technologies
In the Russian Federation allowing to receive coverings with a high threshold
of beam durability to the radiation of lasers so far. Similar coverings are one
of key elements almost of any laser system and, eventually, define such
characteristics of devices as power, reliability, and durability. But it is the
weakest element of a system", - Kotin told RIA Tomsk.

According to him, this year he
received a grant of the "UMNIK" program of 400 thousand rubles for a
development of the production technology of such coverings. By the beginning of
2018 the scientist expects to receive the first practical results. Works are
conducted together with the industrial partner of the higher education
institution – the resident of the Tomsk special economic zone "Crystal
He noted that the developed
technology is intended for the nonlinear crystals which are used as active
elements for laser machines. These crystals differently pass or absolutely
cease to pass light at various external influences. When passing through optical
elements the part of the light is lost, and special coverings allow to reduce
these losses to a minimum.
At the same time, he told, that
nonlinear crystals are usually used in the most hostile environment, ant it
means, more reliable coverings are necessary for them: the structure of
material collapses under the influence of the laser beam and temperature. And
if the existing coverings are designed with a maximum impact of 500-600 MW on
square centimeter, the Tomsk technology will allow to produce the coverings
with the impact of 700-800 MW.

Kotin emphasized that such coverings
will be demanded at the domestic enterprises which are engaged in production of
lasers and studying of laser technologies as there is a great demand for such
coverings. Besides, they will be cheaper than analogs which are delivered from
abroad; the developer is sure about it.
TUSUR Scientists actively research
in the field of photonics, and also together with the industrial partner
participate in work of a profile technological platform. The international
school seminar "Photonics Nano — and Microstructures" took place in
the higher education institution Last week in where were more than 70
scientists from Russia, China, Belarus and Finland.
