title: Suppression of temporal spread of ultrashort pulses in dispersive media by Bessel beam generators.
abstract: Linear-optical solutions to the problem of temporal broadening of ultrashort light pulses propagating in air or in solid optical samples are proposed and tested by computer simulations. A special holographic-element setup is analyzed in detail.
