从激光避雷针的角度来看，飞秒灯丝触发和引导大规模放电的能力已经研究了好几年。本文报道了最近的实验结果，首次表明激光丝不仅能触发和引导放电，而且能使放电偏离正常路径，激光丝还能使火花偏离正常路径，而激光与离激光器较远的电极不接触。正负放电极性之间的比较也揭示了指导机制的重要差异。版权所有2012作者。本文是在知识共享署名3.0未移植许可证下发布的。[http：//dx.doi.org/10.1063/1.3690961]
In the perspective of the laser lightning rod, the ability of femtosecond filaments to trigger and to guide large scale discharges has been studied for several years. The present paper reports recent experimental results showing for the first time that filaments are able not only to trigger and guide but also to divert an electric discharge from its normal path. Laser filaments are also able to divert the spark without contact between laser and electrodes at large distance from the laser. A comparison between negative and positive discharge polarities also reveals important discrepancies in the guiding mechanism. Copyright 2012 Author(s).
