Abstract: 

Based on the parabolic differential equation solution behaviour of the pulse width at half-height in linear second order dispersion media was analyzed. It was shown that rectangular non-chirped pulse width varies non-monotonously with distance and reaches 50–60% initial width at compression length that is equal to 0.44 dispersive length. This compression was shown to be caused by dispersive pulse-edges perturbations that lead to frequency chirp on pulse top. The results of experiment with non-chirped rectangular surface magnetostatic wave pulses in yttrium iron garnet film are presented and are in qualitative agreement with the theoretical results.
