Crystals from Novosibirsk will make Russian military laser more powerful
To do so, the NSU researchers have first investigated physical and optical properties of samples of PTP of foreign origin and defined optimal parameters for plates which allow for creating a regular and accurate domain structure of such crystals. Then, based on these data, a research team of Ural Federal University has succeeded in manufacturing such structures. These structures have been applied as a basis for generating electromagnetic waves with strictly predefined parameters to reach the same results as for foreign PTP structures.
The sources of light based on periodic structures made of PTP operate in the middle range of IR domain, and, therefore, are of great practical interest. Namely, in this wavelength range, the absorption bands of a many explosive and poisonous substances are situated. The gas analyzers based on PTP structures might be useful not only for anti-terrorist efforts but also for detection of leakage of natural gas and liquid hydrocarbons from tubes. The express gas analyzers of high sensitivity will find applications also in medicine. Moreover, the high capacity of laser based on PTP structures could be essential for military applications.
