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.

我们已经使用4ΩD20ED2 nd：YAG激光器的脉冲持续时间为〜6ns的4ΩD20ED2 LASER对实验研究了“ DARC（DC至AC辐射转换器）”。在静态电场和相对论电离方面的相互作用实验中已经观察到电磁波产生。发射的微波脉冲（〜6NS）的频率范围从9.5 GHz到14.1 GHz。输出信号强度与DC偏置电压成正比，功率为2.3。发射的辐射场沿静态电场方向极化。发射辐射的脉冲持续时间与电离激光器的脉冲持续时间一样长。这表明脉冲持续时间在很大程度上取决于激光光的电离过程。
