An energetic study of focused ultrashort Gaussian beams was carried out using the Fresnel diffraction formulae in the frequency domain. Analysis of the encircled energy at the focused plane shows that diffraction spreading of a focused pulsed beam occurs in the limiting case of a ultrashort pulse by comparing it to a cw beam whose frequency is ωm which strongly contributes to the diffracted intensity rather than the carrier frequency ω0.
