“…There is the electron accelerator voltage of 2 × 10 5 V, the compulsory radioactive protection, and cryogenic cooler. Receiving a homogeneous RF discharge under the moderate pressure and high Mach numbers in the gas stream [3] solves the problem related to an e-beam and cryogenic cooler for CO lasers. The active medium is being cooled while it is expanding in the nozzle; a low-current RF discharge is similar to a non-self-sustained discharge [4].…”

“…It was acquired lasing with an RF discharge under excitation in the discharge before the nozzle as well as after it [3,[5][6][7][8][9][10]. Though only in case of a discharge exciting after the nozzle, the supersonic stream parameters allow to restore the pressure in the diffuser to the level of the atmospheric pressure and to apply a commercial compressor for gas streaming and piping.…”

“…Employing an RF discharge in the supersonic stream instead of a non-self-sustained discharge and the gas cooling by its expansion in the nozzle allow to simplify considerably the CO laser design. We have received the lasing on the experimental small-scale facility with an RF discharge in the supersonic stream [3]. In the present work, the parameters of a mode-locked CO laser with a continuous RF discharge in the supersonic stream have been calculated.…”

In the present work, we have suggested a technical solution of a CO laser facility for industrial separation of uranium used in the production of fuel for nuclear power plants. There has been used a method of laser isotope separation of uranium, employing condensation repression in a free jet. The laser operation with nanosecond pulse irradiation can provide acceptable efficiency in the separating unit and the high effective coefficient of the laser with the wavelength of 5.3 μm. Receiving a uniform RF discharge under medium pressure and high Mach numbers in the gas stream solves the problem of an electron beam and cryogenic cooler of CO lasers. The laser active medium is being cooled while it is expanding in the nozzle; a low-current RF discharge is similar to a non-self-sustained discharge. In the present work, we have developed a calculation model of optimization and have defined the parameters of a mode-locked CO laser with an RF discharge in the supersonic stream. The CO laser average power of 3 kW is sufficient for efficient industrial isotope separation of uranium at one facility.
