Investigation of Cold Cathodes for Long Life CO2 Waveguide Lasers.

Abstract

Within a year's time we have extended the life of the 1.5W CO2 waveguide laser from 1500 hours to over 8000 hours. After this period we still find some loose, sputtered cathode material in the laser. This situation can not be tolerated for lasers used in the field. Discharge tube observations indicate that other cathode materials exist that seem to produce sputtering products with better wall adhesion properties. (Author)
