An analysis is made of the conditions favoring formation of a long thin filament of a multiply charged plasma at the caustic of an axicon as a result of optical breakdown of a gas and the conditions for the amplification of light in such a filament.

A study was made of the growth of a laser spark created by focusing a giant laser pulse with an axicon. A spark appeared after 20–50 nsec, depending on its nature, and the radiation emitted by the spark plasma lasted for more than 100 μsec. The ma
