SOLID-STATE ELECTROMAGNETIC RADIATION SOURCE Russian patent published in 2012 - IPC H01S3/16 

FIELD: physics.

SUBSTANCE: solid-state electromagnetic radiation source has a working layer in form of a film of conducting ferromagnetic material, a first electrode made from conducting ferromagnetic material which is in contact with the working layer, and a second electrode made from conducting material which is in contact with the working layer. The working layer of the solid-state source lies on a substrate made from a dielectric or a semiconductor which is transparent for radiation in the operating wavelength range. The second electrode is in form of a solid plate with a through-hole lying on the surface of the working layer. The first electrode is in form of a rod with a pointed end, which is inserted into the hole of said plate such that the face of its pointed end is in contact with the working layer.

EFFECT: higher electromagnetic radiation power.
