Zusammenfassung:	A method for shaping the surface of an optical target, said method comprising the steps of: addressing a ring of laser radiation to the surface of the optical target domain, said laser radiation being of sufficient fluency and energy to phototablate the material forming the body of said optical target domain, sweeping the optically functional portion of said target domain with said laser ring by effectively changing the radius of said ring in a prescribed fashion within the range of the radius of the optical target domain and zero. Procédé de profilage de la surface d'une cible optique consistant à: appliquer un rayonnement laser en forme d'anneau à la surface du domaine optique cible, ledit rayonnement laser présentant une fluence et une énergie suffisantes pour effectuer une photoablation du matériau composant le corps dudit domaine optique cible, et à faire en sorte que l'anneau laser balaye la partie à fonctionnalité optique du domaine optique au moyen de la modification effective du rayon de cet anneau d'une manière prescrite et à l'intérieur de la plage comprise entre le rayon du domaine optique cible et zéro.
