Abstract

Cette invention concerne un dispositif de thérapie par rayonnement laser à faisceau vert à semi-conducteur, lequel dispositif comprend un générateur laser (3) se composant d'un laser à semi-conducteur (4), d'une pompe, d'un cristal de multiplication de fréquences (5), d'une lentille de focalisation (6) et d'une lentille de correction (7), ces éléments étant disposés de manière séquentielle le long d'une trajectoire lumineuse dans la cavité du générateur laser (3). Un rayonnement laser infrarouge d'une longueur d'onde de 808 nm est émis par le laser (4), puis transformé par pompage et par multiplication de fréquences en un laser à faisceau vert d'une longueur d'onde de 532 nm, la sortie étant ensuite connectée par l'intermédiaire d'un dispositif de couplage à fibre optique. Ce laser à faisceau vert peut tuer efficacement certains virus et bactéries pathogènes particuliers dans le sang, activer la superoxyde dismutase des cellules, accroître le métabolisme de la membrane cellulaire, et améliorer ainsi l'immunité du corps humain.
