Paper Abstract

The task about influence optical meteorological condition (OMC) of an atmosphere on conditions of distribution of high power laser radiation (HPLR) can be considered with several, sometimes almost diametrically opposite, points of view. For example task of transmitted of laser through atmospheric path means modeling parameters of radiation, with reference to an atmospheric situation so that to avoid losses of energy, locked by the centers optical breakdown in the channel of laser beam. Hence, the generation of the plasma centers in the channel of laser beam is in this case 'parasitic' effect. In a task of use of laser radiation for posting of the lightning, generation of an extended laser spark on peak of a tower in the given direction - 'useful' effect. Certainly it is impossible to consider the second task as inversion by first. In the report the opportunity of application of results of experiments in real atmospheric path received with the decision of a task of distribution for a task of forecasting of efficiency of creation of a long laser spark in various OMC of an atmosphere is considered. The results of processing of the acoustic response from the centers optical breakdown in an atmosphere are submitted. The received dependences of the characteristics of acoustic signals (amplitude, duration) from parameters HPLR OMC are considered from the point of view of their conformity to available models of formation of an acoustic pulse. The prospects of application of supershort laser pulses in a task lightning control are discussed.
