已经发现激光诱导击穿的阈值受到横向于激光焦点的电场的影响。在空气中，在20托的压力下，600 V/cm的场强被发现完全抑制击穿。在较高的电场强度，电场诱导击穿，而不是抑制它。这些效果被解释为由于电荷去除和电子级联。
The threshold for laser‐induced breakdown has been found to be influenced by an electric field transverse to the laser focus. In air at a pressure of 20 Torr a field strength of 600 V/cm was found to completely suppress breakdown. At higher field strengths the electric field was found to induce breakdown rather than suppress it. These effects are explained as being due to charge removal and electron cascade.
