METHOD FOR GENERATING CONTINUOUS COHERENT RADIATION WITH FREQUENCY OF 2.52 THZ Russian patent published in 2021 - IPC H01S3/00 

FIELD: quantum electronics.

SUBSTANCE: invention relates to quantum electronics. A method for generating continuous coherent radiation of the terahertz range consists in the interaction of directed exciting radiation with the active medium of the sample; in this case, a low-temperature plasma in a gas mixture of xenon and helium is used as the said active medium, in which metastable xenon atoms are produced in the Xe(ls₅) state; the said active medium is placed in a terahertz resonator; as the mentioned directed exciting radiation, radiation with a wavelength of 980 nm or 904.5 nm is used, due to which the transition in xenon atoms is optically pumped, respectively ls₅ → 2р₁₀ or ls₅ → 2р₉, followed by collisional relaxation to the state 2р₁₀; the said continuous coherent radiation with a frequency of 2.52 THz is generated at the transition 2р₁₀ → ls₂, due to the inverse population of the states Xe(2p₁₀) and Xe(ls₂), resulting from the aforementioned optical pumping.

EFFECT: expansion of the arsenal of technical means.
