Title (EN) STRENGTHENED OPTICAL GLASS FILTER
(FR) FILTRE OPTIQUE RENFORCE EN VERRE
Abstract: front page image
(EN)A laminated, optical filter lens (10) having particular application in a high-fluence laser, and a method of forming such lens. The filter lens (10) comprises a core (12) and a cladding (14 and 16), the core (12) having an essentially pure, single, fused oxide composition and the cladding (14 and 16) having a fused oxide composition different from that of the core (12) and having a coefficient of thermal expansion lower than that of the core (12).
(FR)L'invention porte sur un filtre (10) optique laminé ayant des applications particulières dans le domaine des lasers à forte fluence, et sur son procédé de fabrication. Le filtre (10) comporte un noyau (12) et un placage (14, 16). Le noyau (12) est fait d'un unique oxyde fondu sensiblement pur, et le placage (14, 16), d'un oxyde fondu dont la composition diffère de celle du noyau (12), et dont le coefficient de dilatation thermique est inférieur à celui du noyau (12).
