Résumé

We establish analytical expressions that demonstrate that the beam produced after diffraction of a gaussian beam by an opaque disk and collimation by a lens can be approached by a diffraction-free J0 Bessel function. We further demonstrate that a similar analytical expression can be established in the case of femtosecond incident pulses
