ABSTRACT:
The invention relates to a system making it possible to obtain a selective reaction in photochemical processes from laser beams, comprising means for distributing said beams permitting a good utilization of the light energies.
This system comprises in a sealed enclosure: the matter being in the state of a vapor from which it is wished to extract a chemical or isotopic species, laser sources emitting into said enclosure; a beam S.sub.1 permitting a selective excitation of the species to be extracted and a beam S.sub.2 permitting a transformation of said excited species. This system also comprises means for distributing the beams and incorporating means for superimposing the beams S'.sub.1 . . . S.sub.1.sup.(n) with n being an interger at least equal to 1 and for forming several beams S.sub.1 which it is wished to introduce at several points through the vapor to be treated, means for introducing beams S.sub.1 and beam S.sub.2 into the enclosure in such a way that their paths are different and means for inverting them along parallel arms.
Application to the isotopic separation of an atom or molecule, or to the photoisomerization of a molecule.
