  • Laser isotope separation by multiple photon absorption
    Patent number: 4655890
    Abstract: Multiple photon absorption from an intense beam of infrared laser light may be used to induce selective chemical reactions in molecular species which result in isotope separation or enrichment. The molecular species must have a sufficient density of vibrational states in its vibrational manifold that, is the presence of sufficiently intense infrared laser light tuned to selectively excite only those molecules containing a particular isotope, multiple photon absorption can occur. By this technique, for example, intense CO.sub.2 laser light may be used to highly enrich .sup.34 S in natural SF.sub.6 and .sup.11 B in natural BCl.sub.3.
    Type: Grant
    Filed: February 8, 1985
    Date of Patent: April 7, 1987
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: C. Paul Robinson, Stephen D. Rockwood, Reed J. Jensen, John L. Lyman, Jack P. Aldridge, III
