Gas laser oscillator arrangement

摘要

The arrangement includes first (1) and second (2) main electrodes arranged opposite each other, and a pair of electrodes (12) for an initial ionization, which have hollow dielectric reeds (3), rear electrodes (4) arranged in hollow interiors of the reeds, and corona electrodes (5) arranged in contact with outer surface areas of the reeds, at sides of the first main electrode in such way, that they form specific gaps (S1, S2) between them and the main electrode. The arrangement comprises a first (1) and a second main discharge electrode (2) arranged opposite each other, and a pair of electrodes (12) for an initial ionization, which comprise hollow dielectric reeds (3), rear electrodes (4) arranged in hollow interiors of the dielectric reeds, and corona electrodes (5) which are arranged in contact with outer surface areas of the dielectric reeds. A carrier disk (6) is provided for the fastening of the first main electrode and the pair of ionization electrodes. The corona electrodes are arranged at sides of the first main discharge electrode in such way, that specific gaps (S1, S2) remain between them. Laser gas (G) which streams through a main discharge space between the first and the second main electrodes from one side to the other side of the ionization electrodes. The corona electrodes are arranged in such way, that the starting points (11) of the corona discharge at the surfaces of the dielectric reeds is lower than a height (h) of a highest part of the first main electrode.
