Abstract: The propagation features of laser radiation are discussed for the case of axiconic focusing. Issues explored include the nature of gas breakdown in the field of a Bessel laser beam, the gas-dynamic expansion of the breakdown plasma, and how optical discharges and plasma channels are structured.
