This paper presents the results of an experimental and numerical study of filamentation of axicon-focused femtosecond laser radiation in fused quartz. It is shown that the wave-front curvature of the laser beam incident on the axicon affects the number of plasma channels in the filament and the distance between them. The parameters of the solitonlike wave packets (light bullets), such as the peak intensity, duration, and transverse size are independent of the wave-front curvature of the radiation.
