英文摘要
We have experimentally investigated "DARC (DC to AC radiation converter)" using 4ωィイD20ィエD2 light of Nd : YAG laser with a pulse duration of 〜 6ns. Electromagnetic wave generation has been observed in the interaction experiments between a static electric field and a relativistic ionization front. The frequency of the emitted microwave pulse (〜 6ns) ranges from 9.5 GHz to 14.1 GHz. The output signal intensity is proportional to the DC bias voltages with a power of 2.3. The emitted radiation field is polarized along the static electric field direction. The pulse duration of the emitted radiation is as long as that of the ionizing laser. This indicates that the pulse duration strongly depends on the ionizing process by the laser light.
