    "abstract": "A propagation of an ultra-intense short laser pulse in a fiber is\ninvestigated with two dimensional Particle-in-Cell simulations. The fiber is a\nnarrow hollow channel with walls consisting of overdense plasma. In the\nnonlinear interaction of the laser pulse with fiber walls high order harmonics\nare generated. Sufficiently high harmonics, for which the fiber walls are\ntransparent, propagate outwards at certain angle. This is a scheme of a\ngenerator of ultra-short pulses of coherent light with a very short wavelength.",
