PULSED, TRANSVERSELY ELECTRICALLY EXCITED ATMOSPHERIC-PRESSURE GAS LASER (T.E.A. LASER)

摘要

A transversely electrically excited atmospheric pressure gas laser working in a pulsed mode (TEA laser) includes a cooled working gas conducted in circulation, a cooled cathode, an anode arranged at a distance from the cathode, and an open-worked auxiliary electrode arranged therebetween. The cooled cathode is designed as a metallic conducting, elongated cathode plate extending in the direction of the optical axis and the auxiliary electrode is arranged parallel to the cathode in the cathode drop region, in order to produce a glow skin covering the entire cathode.
