Claims

[Claims for Utility Model Registration] A pair of vertically long plate-shaped main electrodes arranged facing each other facing a discharge space, and a plurality of pairs arranged along the vertical side edges of the main electrodes. It is equipped with an auxiliary electrode for pre-ionization, a casing that houses the main electrode and the auxiliary electrode, and a high-reflection mirror and an output mirror that are placed above and below with a discharge space in between. Mirror holders for high reflection mirrors or output mirrors are attached to the top and bottom of the bottom plate so as to cover the laser passage holes, and the mirror holders are equipped with new laser gas to send new laser gas into the casing through the laser passage holes. A TEA-CO ₂ laser oscillation device characterized by being provided with a supply port.
