Abstract

Appts. for combining pulsed beams of radiation, e.g. from pulsed lasers used in sepn. of mixts. of several isotopes, which are inclined to a central axis at a angle which is a small fraction of a radian has a device, pref. with a reflecting surface, arranged at the point where the beams meet the axis to deflect the beams on to a common path. The angle of the beams is pref. 1 degrees. Pref. the reflecting surface can be rotated, and pref. the point where the beams meet the reflecting surface is distinct from the axis of rotation of the surface.
