Abstract

L'invention concerne la formation de volumes de matière inhomogène. Elle se rapporte à la mise en oeuvre d'une absorption d'au moins deux photons, de deux faisceaux séquents par exemple, provoquant la formation d'inhomogénéité dans un volume de matière capable d'exister à deux états fondamentaux. Application à la réalisation d'éléments optiques correcteurs et de lentilles, ainsi que de mémoires tridimensionnelles programmables.
