Russia has created an optical fiber resistant to ultra-high doses of radiation: for space and not only

Today, August 5, researchers from the Ural Federal University (located in Yekaterinburg) officially announced the creation of a special optical fiber that can work even in an environment with ultra-high radiation levels – this was reported by RIA Novosti, citing its sources. Experts have already noted that the latest optical fiber will be in great demand in various space projects – the development can be used to create special devices with protection from impressive ionizing cosmic radiation. However, in fact, there are a lot of areas in which Russian optical fiber can be used – from traditional electronics to projects at nuclear facilities.

For example, employees of the Ural Federal University said that their optical fiber could be embedded in infrared space telescopes. Due to this, scientists will be able to replace massive mirrors and lenses, since the new development allows you to receive and transmit radiation from many space objects. The main advantage of the latest optical fiber in this scenario is durability – the authors of the development suggested that the service life of such an optical fiber would be much higher than the potential life of the telescopes themselves.

The scientists also talked about how exactly they managed to achieve such a significant leap in this direction. Specialists noted that their optical fiber was created on the basis of silver bromide and iodide single crystals – thanks to computer modeling, the developers managed to determine the most optimal conditions for their manufacture in order to produce the most homogeneous optical fibers operating in the infrared range. It is due to the presence of iodine anions in the crystal lattice of silver bromide that the domestic optical fiber received additional radiation resistance, eventually expanding the transmission range of infrared radiation.

Shortly after computer simulations, the researchers were able to obtain experimental confirmation of this claim. And in the future, such fibers can be used in “civilian” areas – in laser surgery, endoscopic and diagnostic medicine, in determining the composition of waste from the nuclear industry. But the space sphere is probably still in the first place.
