Popis:	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 CO 2 and Nd laser.
