TRANSVERSELY ELECTRICALLY EXCITED ATMOSPHERIC PRESSURE GAS LASER WORKING IN PULSES (TEA LASER)

摘要

ABSTRACT OF THE DISCLOSURE:A transversely electrically excited atmospheric pres-sure gas laser (TEA laser) working in pulses includes acooled working gas conducted in circulation, a cooled cath-ode, an anode arranged at a distance to the cathode, andan open-worked auxiliary electrode arranged therebetween.The cooled cathode is designed as a metallically conducting,elongate cathode plate extending in the direction of theoptical axis and the auxiliary electrode is arranged pa-rallel to the cathode immediately thereto, i.e. in thecathode drop region, in order to produce a glow skin cover-ing the entire cathode.
