A radio frequency (RF) excited waveguide gas laser has a hollow wavegide defined by dielectric or lossy materials and metal electrodes coated by thin films with small absorptions so that the metal electrodes are separated from the filling gas and the waveguide loss is very low. With such thin films on the electrodes, a sealed-off, high-power, compact waveguide gas laser having an extended life is realized.
