Abstract
A small-scale installation with automated control based on a compact repetitively pulsed CO2 laser has been developed. It is used to isolate the 14C carbon isotope during development of the reactor graphite purification process. The operating principle of the facility is based on the selective multiphoton laser dissociation method. The precise wavelength tuning is ensured by the design of a special diffraction grating assembly with automatic control. It is shown that the setup functions are much broader, and it can be used to separate the average-mass isotopes and other chemical elements.
