Isotope separation process

摘要

This application discloses a method of separating the isotopes of an element which form a volatile compound having an isotopically shifted but overlapping infrared absorption spectrum. In the method, IR radiation of first and second laser frequencies are employed. The first infrared laser frequency produces a selective excitation of the desired isotope of the compound, while the second infrared laser frequency produces a higher multiphoton excitation which allows conversion of the excited compound.
