ABSTRACT:
In a gas laser, the surface of either or both of discharge electrodes are formed from titanium oxide which provides fine sputtering proof. The discharge electrodes are formed from titanium as a base material having an oxidized surface. Alternatively, the discharge electrodes are formed from molybdenum as a base material with titanium coated and the surfaces are oxidized. In the gas laser of the direct current discharge type, the cathode is formed as described above. Both of cathode and anode are formed as described above in the gas laser of the alternate current discharge type.
