Abstract: A high pressure gas laser is described in which uniform electrical field distribution is obtained for lateral discharge in the gas by employing a capacitor formed within the laser cavity. The laser may be a parallelepiped with capacitor plates forming two opposite rides of the parallelepiped. One of the plates is coated with a ceramic dielectric. Alternatively, the laser may be a conductive circular cylinder with a center electrode, and with a ceramic dielectric coating on the inside of the cylinder. A high voltage source is connected to the laser. Emission occurs when the capacitor charges to a high enough voltage to discharge through the gas. For better charge distribution, the coating may be covered by a resistive layer, or may have a mosaic of isolated conductors thereon.
