METHOD OF OBTAINING POPULATION INVERSION ON IODINE ATOMS Russian patent published in 2015 - IPC H01S3/22 H01S3/953 

FIELD: chemistry.

SUBSTANCE: method of obtaining population inversion on iodine atoms includes optical pumping of a gas stream. Optical pumping is carried out in two steps, where at the first step a gas stream is irradiated with light with wavelength of 490±10 nm, resulting in partial 1-10% dissociation of iodine molecules, followed by irradiation of the gas stream with radiation with wavelength of 1315 nm until full dissociation of iodine molecules and then carrying out gas-dynamic cooling.

EFFECT: avoiding the need to use hazardous reagents and enabling continuous pumping of the working medium.
