ABSTRACT:
In laser apparatus, an amplification section of a laser apparatus, including a cavity bounded by first and second opposing surfaces, closely spaced relative to the dimensions of the surfaces, electrodes for generating an electric field within the cavity and magnetic devices for creating a magnetic field in a direction perpendicular to the surfaces, with provision for shaping the electric field so that the electric field is relatively narrow in the dimension parallel to the magnetic field compared to the dimension perpendicular to both the magnetic field vector and the electric field vector established between electrodes within the cavity. The electrodes extend over a distance greater than the spacing between electrodes. An electrical discharge is established with the magnetic field exerting a force on the discharge to move the discharge parallel to the surfaces with the predetermined magnetic field strength causing the discharge to become uniform and stable. One embodiment utilizes two generally planar surfaces to form the cavity, while another embodiment utilizes two concentric cylinders to form the cavity.
