CA 2430608
The present invention is directed, in part, to a carbon dioxide laser resonator gas comprising carbon dioxide, helium, and nitrogen and having a total halocarbon concentration less than about 100 parts per trillion. In one embodiment, the total halocarbon concentration is less than about 50 parts per trillion. The laser resonator gases, laser systems, and methods of the present invention provide high efficiency and high power laser light while reducing the cost of maintenance and improving the performance of a laser system by limiting the total concentration of halocarbon.
La présente invention vise en partie un gaz de résonateur laser au dioxyde de carbone qui comprend du dioxyde de carbone, de l'hélium et de l'azote, et qui présente une concentration d'halocarbure totale inférieure à environ 100 parties par trillion. Dans une version, la concentration d'halocarbure totale est inférieure à 50 parties par trillion. Les gaz du résonateur laser, les systèmes laser et les méthodes de la présente invention fournissent un rendement élevé et une lumière laser à haute énergie, tout en diminuant les frais d'entretien et en améliorant la performance d'un système laser en limitant la concentration totale d'halocarbure.
