A starting device for a sealed, cross-flow gas laser for operating at least wo electric discharges simultaneously in a single laser cavity using primary fins between the cathodes and anodes of the cavity as intermediate electrodes. A series of high voltage relays and resistors are placed in parallel with the discharge path between adjacent fin electrodes and by switching out pairs of relays current is coupled to the discharge path, one fin at a time.

Gas laser starting

A gas laser is constructed of discrete segments in such a manner that the s flowing through the active region of the laser is introduced from a plenum chamber from whence it flows annularly into the active region and travels through the region both to the left and right of the input until it reaches the first output region. From there the gas flows annularly out into a shaping region and thence into the output plenum.
