This patent describes a waveguide laser arrangement comprising: a housing bounding an internal space; a first electrode having a major surface situated in and facing into the internal space; a dielectric waveguide body juxtaposed with the major surface of the first electrode and bounding at least one elongated laser cavity; a second electrode juxtaposed with the waveguide body across the laser cavity from, and forming a capacitor of a predetermined capacitance with the first electrode; a dielectric spacer body juxtaposed with the second electrode across from the waveguide body and having one major surface facing toward, and another major surface facing away from, the second electrode; distributed inductance means including a plurality of flat inductor coils distributed longitudinally of the laser cavity along and in juxtaposition with the other major surface of the spacer body and each having spaced first and second ends and a predetermined electric inductance between the ends; means for supplying first electric potential to the first electrode and a second electric potential to the second electrode, at least one of the electric potentials alternating at a predetermined frequency relative to the other.
