Title (EN) PHOTO-INDUCED TEMPERATURE GRADIENT ZONE MELTING
(FR) FUSION DE ZONE A GRADIANT DE TEMPERATURE PHOTO-INDUIT
Abstract: front page image
(EN)A temperature gradient zone melting process wherein the temperature gradient is established substantially across only the molten zone (33) by preferentially heating the molten zone. In a specific embodiment, the mechanism for inputting heat to the molten zone (33) involves exposing a substrate (31) to optical radiation (32 or 32 and 38) of a wavelength and magnitude for which the molten zone is absorptive and the remainder of the body is transparent. The molten zone thereby migrates through the body toward the source of optical radiation.
(FR)Dans un procede de fusion de zone le gradiant de temperature est etabli sensiblement seulement a travers la zone de fusion (33) par chauffage preferentiel de la zone de fusion. Dans un mode specifique de realisation, le mecanisme de chauffage de la zone de fusion (33) consiste a exposer un substrat (31) a une radiation optique (32 ou 32 et 38) d'une longueur d'onde et d'une intensite pour lesquelles la zone de fusion est absorbante et le reste du corps transparent. La zone de fusion se deplace au travers du corps vers la source de radiations optiques.
