Few-cycle laser-pulse collapse in Kerr media: The role of group-velocity dispersion and X-wave formation Academic Article uri icon

abstract

  • We study ultrashort laser-pulse propagation and filamentation dynamics in dispersive Kerr media. We identify the regime for which the filamentation threshold (Pth) is considerably higher than the critical power (Pcr) for monochromatic beam collapse in pure Kerr media. In particular, we compare the threshold for the formation of filaments with that for the formation of X -waves. At powers Pcr
