Scientists from St. Petersburg State University Instrumentation University have found a way to create a super-centered laser beam for better communicating in space. This will help increase the range and reduce the energy consumption of space communication systems. The GUAP told GAAP about this.
The specialists used crystals grown by the Institute of Inorganic Chemistry of the Russian Federation to scan the light rays, which are not subject to optical phenomenon, such as diffraction. The diffraction affects the properties of the beam, in particular, on its deviation. The greater the distance, the greater the beam deviation and so bad the quality of the connection. Additional methods are required to improve the sensitivity of receivers.
Guap team has created a test model of acousto-optical device. This is a special device that comprehensively monitors the intensity and implementation of light rays and allows you to move and scan this beam into space. The sample was tested in real conditions.
The existing space communication systems operate on the traditional Gaussian optical rays. But in the space communication systems, it is necessary to ensure the recipient of the recipient and transmitter. This can be obtained through acoustopics (a branch of physics that studies the interaction of sound and electromagnetic channels). This can be used to introduce programs in external space, using fundamentally new diffraction laser rays, which allows you to increase communication domain and reduce system energy consumption, "says Vasily Kazakov.
