Abstract

This study utilizes the Kerr effect in the analysis of a pulsed electric field (intensity ~108 V/m, limited by the liquid dielectric strength) in deionized water at the sub-nanosecond time scale. The results provide information about voltage waveforms at the field-producing anode (160 kV peak, du/dt > 70 kV/ns). The analysis is based on detecting the phase shifts between measured and reference pulsed laser beams (pulse width, 35 ps; wavelength, 532 nm) using a Mach–Zehnder interferometer. The signal-to-noise ratio of the detected phase shift is maximized by an appropriate geometry of the field-producing anode, which creates a correctly oriented strong electric field along the interaction path and simultaneously does not electrically load the feeding transmission line. The described method has a spatial resolution of ~1 μm, and its time resolution is determined by the laser pulse duration.
利用具有皮秒分辨率的克尔效应测定水中的高瞬态电场
本研究利用克尔效应对去离子水中的脉冲电场(强度约为 108 V/m,受液体介电强度限制)进行了亚纳秒时间尺度的分析。结果提供了产生电场的阳极的电压波形信息(峰值 160 kV,du/dt > 70 kV/ns)。分析的基础是使用马赫-泽恩德干涉仪检测测量激光束和参考脉冲激光束(脉宽 35 ps;波长 532 nm)之间的相移。场产生阳极的适当几何形状可最大限度地提高检测到的相移信噪比,该阳极可沿着相互作用路径产生方向正确的强电场,同时不会对馈电传输线造成电负荷。所述方法的空间分辨率为 ~1 μm,时间分辨率由激光脉冲持续时间决定。
