In this work we discuss the propagation of the wave radiation focused by the axicon, and analyze optical discharges created by laser Besselian beam in gases, fluids and on solid surfaces. We consider formation processes of discharges, properties and structures of the plasma channels. Also, we describe the methods of research of Besselian beams, breakdowns, discharges and plasmas created by the beams.

The optical discharge arisen under the action... (More)
