Abstract

It is demonstrated that a short microwave pulse (/spl sim/6 ns) is generated from cw or long pulse microwave source (9 GHz) by the laser produced overdense plasma. The cw microwave propagating in the waveguide is sliced by laser produced plasma at two different points along the waveguide. The generated pulse duration is determined by the group velocity of the microwave in the waveguide and the length between two points. Furthermore, twice the power is generated by adding the two pulses by this mechanism. The results are in good agreement with theoretical prediction.
