An apparatus and a system for the sequential combination of a plurality of radiant-energy pulsed beams

Description

The present invention relates to combining pulsed optical beams with a view to increasing the recurrence frequency thereof, and more especially, to a device for optically compensating angular fluctuations resulting from the rotation of the combination members. The system comprises several lasers mounted in star fashion about a rotating reflector combining sequential pulses into a single beam directed towards corrective members driven, at half the reflector speed, in opposite directions so as to compensate the rotation of the deflection plane, on the one hand, and the deflection itself due to the rotation of the combination optical members during laser pulses, on the other hand. Such a system is specially suitable for isotope separation plants using laser energy

Abstract (French)

La presente invention concerne la combinaison des faisceaux optiques pulses en vue d'augmenter leur frequence de recurrence, et plus particulierement un dispositif de compensation optique des fluctuations angulaires dues a la rotation des organes de combinaison. Le systeme comprend plusieurs lasers montes en etoile autour d'un reflecteur tournant qui combine les impulsions sequentielles en un faisceau unique dirige vers les elements de correction qui sont entraines a la moitie de la vitesse du reflecteur et dans des sens opposes pour compenser d'une part la rotation du plan de deviation et d'autre part la deviation elle-meme due a la rotation de l'optique de combinaison pendant la duree des impulsions laser. Un tel systeme est particulierement applicable aux installations de separation isotopique par energie laser
