实验研究了影响高压电球-球间隙激光触发的参数的影响。主要关注的是激光脉冲到达和电流流过差距之间的延迟时间。该延迟被研究为总激光束功率（0-80 MW）;介电气体（SF6、N2、空气）;气压（100-1400 Torr）;电极间距（0.4-1.5 cm）;间隙电场（10-100 kV/cm）;以及两个5 cm直径不锈钢球之间的焦点位置的函数。延迟时间小于10纳秒，观察到在SF6在大气压与相应的低抖动。对于所研究的情况下，延迟时间与电场，气体压力和焦点距离阳极表面成反比。在一定的激光束功率以上，延迟时间对于所研究的范围不是激光功率的显著函数。激光触发的应用进行了讨论，目前和未来的研究领域的描述。
The influence of parameters affecting the laser triggering of a high voltage electrical sphere‐sphere gap has been experimentally investigated. Of primary interest was the delay time between arrival of the laser pulse and current flow across the gap. This delay was studied as a function of total laser beam power (0–80 MW); dielectric gas (SF6, N2, air); gas pressure (100–1400 Torr); electrode spacing (0.4–1.5 cm); gap electric field (10–100 kV/cm); and focus point location between two 5 cm diam stainless steel spheres. Delay times less than 10 nsec were observed in SF6 at atmospheric pressure with corresponding low jitter. For the cases studied delay times varied inversely with the electric field, gas pressure, and focus point distance from the anode surface. Above a certain laser beam power the delay time was not a significant function of laser power for the range studied. Applications of laser triggering are discussed with a description of current and future research areas.
