The problem of diffraction of few-cycle light pulses is solved by means of a perturbative technique. The propagated field is expressed as a series of correction terms to the field obtained from diffraction laws for many-cycle pulses. The features previously reported for diffraction of ultrashort pulses are reproduced by first- and second-order corrections.
