摘要

METHOD AND DEVICE FOR EXCITATION AND SELECTIVE DISSOCIATION BY ABSORPTION OF LASER LIGHT In a method of excitation and selective dissociation by absorption of the monochromatic light emitted by a highpower laser, the laser light is sent at a frequency ?1 into an isotopic mixture of gaseous molecules in which a certain number of molecules exhibit transitions between two vibrational levels corresponding to a predetermined isotope and separated by an energy interval .DELTA.E1 = 2h?1. The molecules of a predetermined isotopic species are thus excited preferentially until subsequent dissociation into a number of constituents.
