  • Apparatus for exciting a plasma in a column of gas by means of microwaves, in particular for providing an ion laser
    Patent number: 4698822
    Abstract: A waveguide (130) is coupled to a tubular member (2) by a gap (139) suitable for generating an intense surface wave in a gaseous mixture contained in the tubular member (2). Short circuits (110 and 120) delimit the plasma, thereby generating very high intensity standing microwaves, which increase the energy density of the plasma. An ion laser effect can then be observed, in particular in a mixture of argon and helium, together with optional krypton.
