Changes in the structure and composition of the surface of a cathode upon long-term interaction with helium‒neon plasma

Аннотация

The findings of an investigation into the impact of ions on the atomic state of the upper layer of He‒Ne laser cathodes are presented. The research results are obtained using electron-probe microscopy, X-Ray photoelectron spectroscopy, and Auger spectroscopy, including the scanning mode. Changes in the surface compositions of the cathodes and active-element mirrors of lasers are revealed before and after tests.
