diffraction broadening

The temporal and spectral properties of Bessel-Gauss pulsed beams with constant diffraction length in a linear dispersive medium are studied. It is shown that by a suitable choice of the spatial parameter β, Bessel-Gauss pulsed beams propagate along the axis without noticeable pulse broadening.
