ABSTRACT:
A gas operated laser is disclosed which comprises two main electrodes facing each other and connected with a single feeding capacitor both for the preionization and for the main laser discharge, wherein the gas preionization in the laser vessel is obtained by a corona discharge generator comprising a dielectric tube along the outside of which a conducting wire is stretched to contact the outer surface of the tube which conductor connects with one of the discharge electrodes while a thin conducting rod inserted in said tube connects with the other discharge electrode. As a first alternative an edge of a conducting material shape is used as a substitute for said conducting wire. As a second alternative the side sharp edge of one of the main electrodes is used in lieu of said conducting wire.
