Abstract

Appareil de production de faisceau laser comportant un segment de septum disposé longitudinalement à l'intérieur de la structure tubulaire de l'appareil. Le septum permettant la dissipation par rayonnement de la chaleur produite à l'intérieur de la structure tubulaire et permettant la production d'impulsions de faisceaux laser relativement uniformes de manière à réduire au minimum ou à éliminer les retards d'impulsion dans le sens radial (effet de chevron).
