CA 2661255

A method of coupling optical energy comprising: generating a first beam of optical energy; generating a second beam of optical energy coherent with the first beam; polarizing optical energy from the first and second beams in a same direction; and transmitting the polarized optical energy from the first and second beams into a photorefractive body so that the energy interferes in the body to generate an interference pattern that is extant in substantially all the volume of the body.

La présente invention concerne un procédé de couplage d'énergie optique qui consiste en : la génération d'un premier faisceau d'énergie optique, celle d'un second faisceau d'énergie optique cohérent avec le premier, la polarisation de l'énergie optique provenant du premier et du second faisceau dans la même direction, et la transmission de l'énergie optique polarisée à partir du premier et du second faisceau dans un corps photoréfractif afin que l'énergie fasse interférence dans le corps pour générer un motif d'interférence qui se déploie dans pratiquement tout le volume du corps.
