Russian scientists plan to switch on a laser “star” in space, RIA Novosti informs. Actually, it is going to be a pointed laser beam beyond the atmosphere which is to provide the opportunity to calibrate optical telescopes.
Evgeny Dianov, Director of the Fiber Optics Science Center, explains that on the ground it is rather difficult to calibrate telescope due to air disturbances. The artificial light source beyond the atmosphere will help avoiding this phenomenon.
According to Dianov, the natural lamp already exist at the altitude of 100km. It is a sodium layer, which only needs to be illuminated by yellow light to initiate self-radiation.
Russian scientists have developed bismuth fiber laser capable of accomplishing this objective.
