摘要

本文介绍了一种测量和分析激光系统电磁干扰问题的新方法。系统地测量了高压脉冲激光源周围的辐射磁场。磁场矢量在三维空间中按一定间隔测量。通过插值得到三维磁力线，并绘制成可视化图。利用基本麦克斯韦方程的数学工具用于预测在感兴趣的三维体积中负责磁场通量线的传导电流密度大小。电流密度图显示并突出显示了产生电磁干扰辐射的重要位置。用示波器记录辐射波形的特征。所有测量均使用EMCO的近场探头，并使用标准模拟代码进行系统分析计算和分析绘图。下面详细阐述了实验、测量和分析。

Novel methodology to analyze the source causing electromagnetic interference problem in a LASER system

This paper is intended to report the novel approach in measurement and analysis of electromagnetic interference problem in LASER system. Measurement of radiated magnetic fields around high voltage pulsed LASER source is taken systematically. Magnetic field vectors are measured at regular intervals in 3-D space.3-D magnetic field lines are obtained by interpolation and plotted for visualization. Mathematical tool utilizing the basic Maxwell's equation is used to anticipate the conduction current density magnitudes responsible for the magnetic field flux lines in 3-D volume of interest. Current density plots show and highlight significant locations contributing to EMI radiations. Signature of the radiated waveform is also recorded using oscilloscope. Near field probe set from EMCO is used for all the measurements and standard simulation code is used for systematic analytical calculation and plotting of the analysis. Details of the experiment, measurement and analysis are elaborated below.
