Abstract

L'invention concerne un amplificateur laser à excitation transversale sous pression atmosphérique, constitué par un système d'électrodes comportant une électrode centrale 11 opposée à deux électrodes externes 10 et 14, disposées dans la cavité résonnante d'un boîtier constitué par deux cylindres creux concentriques 2**II et 2** III séparés par un diélectrique 2**IV et par deux parois frontales 8 dont l'une porte des organe optiques réfléchissants et l'autre un miroir fléchissant 18 et un miroir transparent 21, en fonctionnement en laser, tandis qu'en fonctionnement en amplificateur, ces miroirs sont remplacés par des fenêtres laissant passer la radiation laser amplifiee.The invention relates to a laser amplifier with transverse excitation at atmospheric pressure, consisting of a system of electrodes comprising a central electrode 11 opposite two external electrodes 10 and 14, arranged in the resonant cavity of a housing consisting of two concentric hollow cylinders. 2 ** II and 2 ** III separated by a dielectric 2 ** IV and by two front walls 8, one of which carries reflective optical members and the other a bending mirror 18 and a transparent mirror 21, in laser operation , while in amplifier operation, these mirrors are replaced by windows allowing the amplified laser radiation to pass.
