通过电弧放电或激光照射进行连接或切割的金属零件远程加工技术有着悠久的传统，目前仍在进行深入的研究。在需要高功率处理的应用中，这两种方法都表现出某些优点和缺点，这使得它们特定于给定的任务。虽然有几种混合方法试图结合这两种技术的优点，但在提供固定的放电方向方面，没有一种方法像超短脉冲激光产生的等离子体细丝触发的放电那样成功。在这项工作中，我们研究了激光灯丝引导放电的空间和时间方面，并给出了灯丝产生和放电电压的电建立之间的较高时间延迟，以实现成功的灯丝触发放电。
Remote processing of metallic workpieces by techniques based on electric arc discharge or laser irradiation for joining or cutting has a long tradition and is still being intensively investigated in present-day research. In applications that require high power processing, both approaches exhibit certain advantages and disadvantages that make them specific for a given task. While several hybrid approaches exist that try to combine the benefits of both techniques, none were as successful in providing a fixed electric discharge direction as discharges triggered by plasma filaments generated by ultra-short pulsed lasers. In this work we investigate spatial and temporal aspects of laser filament guided discharges and give an upper time delay between the filament creation and the electrical build-up of a dischargeable voltage for a successful filament triggered discharge.
