Abstract
Abstract METHOD AND DEVICE FOR EXCITATION AND SELECTIVE DISSOCIATION BY ABSORPTION OF LASER LIGHT Abstract of the Disclosure In a method of excitation and selective dissociation by absorption of the monochromatic light emitted by a high-power 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 vibra-tional 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 preferential-ly until subsequent dissociation into a number of constituents.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
84 words
A method of excitation and of selective dissoci-ation by absorption of the monochromatic light emitted by at least one high-power laser, wherein the excitation is effected by light sent from the laser at a frequency ?1 into an iso-topic mixture of gas molecules in which a certain number of said molecules exhibit transitions between two vibrational levels corresponding to a predetermined isotope and separated by an energy interval .DELTA.E1 = 2h?1 and wherein the molecules of a predetermined isotopic species are thus preferentially excited.
Claim 2
Independent Claim
84 words
A method of excitation and of selective dissoci-ation by absorption of the monochromatic light emitted by at least one high-power laser, wherein the excitation is effected by light sent from the laser at a frequency ?1 into an iso-topic mixture of gas molecules in which a certain number of said molecules exhibit transitions between two vibrational levels corresponding to a predetermined isotope and separated by an energy interval .DELTA.E1 = 2h?1 and wherein the molecules of a predetermined isotopic species are thus preferentially excited.
Claim 3
Dependent Claim
65 words
A method of excitation and of selective dissoci-ation by absorption of the monochromatic light emitted by at least one high-power laser, according to Claim 1, wherein another light is sent into said mixture additionally and simultaneously at a frequency ?2 so that after said other light is sent into said mixture said molecules of a prede-termined isotopic species are dissociated into a number of constituents.
