The technical solution of a CO laser facility for industrial separation of uranium used in the production of fuel for nuclear power plants is proposed. 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's 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 a 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.
