Patent

CA 2226780

A method of producing glasses with useful optical transmission characteristics includes the steps of melting a charge comprising group III and group IV chalcogenides. Addition of group I and group II halides enhances the solubility of rare earth dopants and permits the fabrication of stable lasers and amplifiers incorporating these glasses.

L'invention porte sur un procédé de production de verres dotés de propriétés de transmission optique efficaces, consistant à faire fondre une charge comprenant des chalcogénures des groupes III et IV. L'adjonction d'halogénures des groupes I et II accroît la solubilité de dopants à base de terre rares et permet la fabrication de lasers et d'amplificateurs stables dans lesquels figurent ces types de verre.
