Paper Abstract

To define more precisely the requirements to electric- physical parameters of laser-generated plasma channel needed to trigger a lightning, the analysis of the experimental data on laser-guided long gap discharges is used. The analysis is based on the developed theoretical model of the channel interaction with thunderstorm electrical fields. Two modes of leader progression form a tip of the channel are considered. The obtained data allows determining the principal conversion conditions of the channel into a leader channel. To maintain the plasma channel conductivity during the modes, two laser pulses is supposed to be used. The suggestion was tested experimentally by the use of CO2 and Nd laser.
