Abstract:
A laser cathode is formed by placing a conductive hemisphere on the side of the lasing cavity. Material is sputtered from the hemisphere to form a conductive layer on the cavity side and on the seal which bonds the hemisphere to the side. A protective oxide layer is formed on the sputtered layer and the hemisphere by filling the cathode with oxygen and passing a current through it.
