In a DC to AC radiation converter (DARC) source, a short microwave wave pulse was emitted by the interaction between a periodic electrostatic field and a laser-produced ionization front. An emission frequency was observed from 8 to 42 GHz and depended on a plasma density, a perpendicular DC magnetic field strength, and a cut-off frequency (i.e., boundary effect) of the rectangular waveguide, respectively. The short THz pulse emission from a femtosecond-laser-pumped DARC source was also demonstrated by use of a 150-fs Ti:sapphire laser pulse.
