Abstract
A sealed structure laser apparatus is disclosed which utilizes corona discharge as a pre-ionizing means wherein the laser discharge space is defined by a dielectric material channel with C cross section and one of the two discharge main electrodes is located along the inner wall of the C channel opposite the C aperture while the other electrode confronts said aperture from the outside of the channel the latter being enveloped by a conducting material grid, two opposite slits being defined between the two edges of said C channel gap and a dielectric material wall located in front of said gap. The exhausted mixture is recycled through an eccentric space defined between two cylindrical walls with parallel axes, the narrower section of said space being partially intercepted by the side walls of said C channel and by said dielectric wall whereby the gaseous mixture is compelled to flow through said slits to enter the laser space and leave the same, the larger section of the eccentric space being utilized for receiving the propelling and reconditioning means of the gaseous mixture, such as fans, coolers etc.
