Abstract

Dispositif pour la photochirurgie et en particulier pour la kératotomie de l'oeil, comportant une source lumineuse operatoire, dont la lumière est applicable sur la région du tissu à opérer. Le dispositif ci-décrit est caractérisé en ce qu'il fait appel pour la production de lumière dans une plage de longueur d'ondes comprise entre 2,7 mum et 3,3 mum à une source lumineuse opératoire comportant une cellule Raman à pompage par laser pulsé. Il est ainsi possible d'obtenir un rayonnement dans la plage avoisinant 3 mum, dont la puissance autorise la pratique de la photochirurgie et dont la "qualité de rayons" permet une focalisation remarquable.
