dc.descriptionA method of formation of the tightly confined distortion-free fs pulses with the step-like decreasing of intensity under the finite-length propagation in free space is described. Such pulses are formed by the Fresnel source of a high refraction-index waveguide. The source reproduces in free space a propagation-invariant (distortion-free) pulse confined by the waveguide. Converse to the case of material waveguides, when the pulse goes out from the Fresnel (virtual) waveguide its shape is not changed, but the intensity immediately drops down to the near-zero level.
