Abstract

The chirped light pulse dispersion under diffraction by a volume transmission grating has recently been considered in Ref. ¹. In the given paper we analyze the problem of a chirped pulse scattering by reflection gratings when the pulse spectral width compares with the grating passband. By analogy with Ref. ¹ one can suppose that this spectral region is the most attractive for observation of dispersion effect on pulse temporal profiles. Under these circumstances, both phase and magnitude of grating spectral functions are strongly varied over incident pulse spectrum and, consequently, the conventional approach considering the variation of the phase term, proves to be suitable only for qualitative estimations. Thus, a rigorous procedure of time domain analysis should be applied.
