The characteristics of high-power terahertz beams in new laser systems can be controlled using silicon and diamond optical elements created at the Samara University.
Researchers have created a wide range of optical elements that allow the manipulation of terahertz laser radiation. According to them, silicon and diamond diffractive optical elements for the terahertz range were created for the first time, which makes it possible to form powerful beams with specified characteristics (including the so-called “rotating beams”) and focus radiation into specified areas of space.
Terahertz radiation has unique properties for optoelectronics, scientists from the Samara National Research University named after Academician S.P. Korolev told Sputnik. They have developed efficient methods for calculating and creating optical elements that operate in the terahertz range of the electromagnetic spectrum, located between the infrared and microwave ranges.
According to the authors of the research, the development can be applied in materials processing, the creation of optoelectronic devices for information processing, as well as in telecommunications. The research results were published in the collective monograph of the Russian Academy of Sciences "Terahertz Photonics".
