ABSTRACT:
A system for producing repetitive stimulated emission pulses of coherent electromagnetic radiation which operates in a traveling wave mode is disclosed. Each pulse of coherent electromagnetic energy is produced by applying a single high voltage pulse to a plurality of pulse transmission lines of progressively greater electrical lengths which are connected at spaced points to electrodes extending parallel to and disposed on opposite sides of a discharge channel which contains a laser type medium. As a result, the pulse is applied to successive points along the discharge channel as the stimulated radiation wave front approaches the respective points, providing optimum efficiency. A number of such systems can be cascaded to produce theoretically unlimited power. In the preferred embodiment, the transmission lines are strip transmission lines formed by printed circuit techniques ad include impedance matching connections at the electrodes to provide enhanced efficiency. The rapid rise pulse is applied to the transmission lines by a thyratron or other switching device.
