ABSTRACT:
Apparatus for the distribution of laser beams used during a selective reaction in a process for isotope separation by lasers. The system comprises in an enclosure (10), a material in the form of a vapor flow, from which it is wished to extract one species, and laser sources (12) supplying pulses along beams S1 . . . Sn at selective excitation wavelengths .lambda.1 . . . .lambda.n and along a beam St at wavelength .lambda.t permitting a transforming of said excited species. The system incorporates partial reflection mirrors (Mi) arranged in such a way that the transmitted and reflected beams S1 . . . Sn, St are superimposed. A first part (P1) of these beams is directed to the enclosure and a second part (P2) to the mirror (Mi+1). Return means (14) make it possible to adjust the length of the path in enclosure (10) between two mirrors (Mi) and (Mi+1).
