Investigation of cold cathode and RF excitation for long life CO2 waveguide lasers
Abstract
This report describes a Ag-Li compound cathode for the longitudinally d.c. excited, low power, CO2 waveguide laser. Discharge tube results with this cathode produced an acceptable gas composition over a period of 10,000 hours. The sputtering rate was quite low and, most importantly, the sputtering products did adhere quite well in the form of a thin film on the closet, cooler surfaces.
