摘要： In a CO2 laser a pre-ionizer is assembled in a flange configured to be attached to a laser-gas enclosure of the laser over an aperture in a wall of the enclosure. An aperture in the base of the flange is aligned over the aperture in the enclosure wall. The aperture in the pre-ionizer flange is covered by a ceramic membrane. A disc electrode is in contact with the ceramic membrane on a side of the membrane outside of the laser-gas enclosure. An RF potential applied to the disc electrode creates a corona discharge on the side of the ceramic membrane inside the enclosure. The corona discharge ionizes laser gas in the enclosure before RF power is applied to electrodes of the slab laser.

摘要： A low inductance, hermetically sealed, RF shielded feed-through is provided for exciting low impedance discharges associated with high power CO2 slab lasers. The feed-through mechanically obtains RF contact, preferably, at the center of the length of the electrodes that are inserted within the long laser housing, thereby making it easier to obtain a uniform electric field distribution along the length of the electrodes.
