  • High-performance gyrotron for production of electromagnetic millimeter or submillimeter waves
    Patent number: 4926094
    Abstract: This invention relates to a high-performance gyrotron for the production of electromagnetic millimeter or submillimeter waves with a quasi-optical resonator. The latter is formed by two concave mirrors (1, 2) placed mutually opposite one another on an optical axis. For increasing the decoupling efficiency as well as for reducing the radiation into the environment the quasi-optical resonator is placed in a housing (4), which at least in sections is electrically conductive.
