<p>An arrangement for discharge of electricity (11-20) or lightning in the atmosphere to prevent formation of space charges that would reduce the strength of electric fields therein by transmitting through a path in the atmosphere one or more first laser pulses (11) of wavelength essentially within the ultraviolet range and of duration sufficient to create an electrically conductive ionized channel in the atmosphere and simultaneously transmit in the path one or more second laser pulses (13) of longer wavelength than the ultraviolet pulses to maintain the conductivity of the channel for a time long enough for lightning to occur therein.</p> |
