Abstract

A device for distributing laser beams used in an isotopic separation method. The plurality of laser beams S.sub.n used in the process; where n is a whole number at least equal to 2, are divided by means of a plurality of partially reflecting mirrors and superimposed by suitable dichroic mirrors. The superimposed beams, during several passages, are sent into a reaction chamber. When one of these beams has its fluence equal to the saturation fluence, a new part of the beam is superimposed onto the beams. This is accomplished by means of a suitable dichroic mirror. The interference between this new part and the residual beam having traversed the chamber are avoided. A specific application is for the isotopic separation of uranium vapor by laser beams.
