First observation of generation in the backward wave oscillator with a 'grid' diffraction grating and lasing of the volume FEL with a 'grid' volume resonator

摘要

First observation of generation in the backward wave oscillator with a "grid"diffraction grating and lasing of the volume FEL with a "grid" volume resonatorthat is formed by a perodic set of metallic threads inside a rectangularwaveguide is considered.
