Abstract

To study the possibility of triggering lightning with a laser plasma,laboratory laser-induced discharge experiments have been carried out and the following results were obtained. Both long straight and zigzaglaser induced discharges between rod-rod electrodes were realized andthe effective guiding effect of laser channels for electrical discharges was confirmed. With plane-plane electrode configuration, the investigation concerning the necessary condition for initiating and guidinga streamer reveals that the necessary electric field for initiating astreamer with a laser plasma depends closely on the absorbed energy used to produce laser plasma channels, the minimum electric field is about 200 kV/m, and that the necessary electric field for guiding a streamer by a laser plasma is lower than that for initiating a streamer and the minimum electric field is about 170 kV/m. We propose to use the local electric field near the top of a grounded tower as the necessaryfield for a laser-produced channel to trigger an upward leader and have proved that this is feasible.
