Investigation of Cold Cathodes for Long Life CO2 Waveguide Lasers,

Abstract

We have proposed to solve the life problems of the low power longitudinally DC excited, CW wave guide laser. The problem areas that presently limit the life of this laser are listed below: The requirement of a cold cathode technology that allows one to maintain the proper gas composition over a long period of time. These cathodes have to have a low sputtering rate and procedure deposits that are stationary and well attached to harmless areas in the neighborhood of the cathode. No mirror deposits can be tolerated. Mirror intensity limits have to be known. Proper sealing techniques are absolutely necessary for long actual laser-life as well as shelf life.
