Any ultrafast laser pulse is fully defined by its intensity and phase, either in time or frequency domain. Propagation in any media, inclusive of air, results in distortions of phase or amplitude. Large distortions in phase can be introduced by propagation of the beam even through optical elements with very low absorption such as lenses or prisms. This effect is frequently called temporal chirp and is due to chromatic (i.e. wavelength-dependent) dispersion.
