SYSTEM ENABLING SELECTIVE REACTION IN PHOTOCHEMICAL METHOD BY LASER INCORPORATING MEANS FOR DISTRIBUTING LASER BEAM

摘要

The invention relates to a system permitting the obtaining of a selective reaction under photochemical processes using laser beams, comprising means for the distribution of these beams allowing good use of the light energies. & br / & this system comprises in a closed enclosure 9: the body to the vapour state, it is desired to extract a chemical species, or an isotopic, laser sources emitting in the enclosure 9: a beam s1 enabling a selective excitation of the species to be extracted, and a beam s2 making it possible to a transformation of the excited species. This system also includes means for distributing the bundles comprising: means 11 for superimposing the beams s ′ 1.. s1 * * (n) with n an integer equal to at least 1 and to constitute a plurality of beams s1 which is introduced at several locations through the steam to be treated, means 13 for introducing the beams s1 and the beam s2 in the chamber 9 so that their path are different and the means 17, 19, 21 to fold them according to the arm 15 which are parallel. & br / application of the isotope separation an atom or a molecule or photoisomerisation of a molecule. & br / (see appended drawing in bopi) & br / & & br /
