Abstract:

To form plasma antennas in various radio and telecommunication devices it is necessary to increase the relaxation time of laser breakdown centers. To overcome this problem, the processes occurring in aerodisperse media containing solid microparticles during interaction with laser radiation are considered. The decay times of plasma with aerosol particles under the influence of nanosecond and microsecond laser pulse have been analyzed. The influence of the electron shell around solid microparticles on the creation of a continuous ionization zone in the aerosol atmosphere formed by overlapping plasma halos around microparticles has been evaluated. The conditions necessary for the creation of a long ionized channel formed by breakdown centers during explosive evaporation of atmospheric microparticles in the zone of influence of a nanosecond pulse of a CO₂ laser and further maintenance of the formed plasma by the radiation of a microsecond laser are considered. A scheme of an experimental setup for creating a long ionized channel in an aerosol atmosphere is suggested. The results can be used for creation of wireless communication channels in the atmosphere.

Keywords:
