Multipulse excitation of a resonant medium by a laser field is considered. It is shown that one stable long-lived grating with an ultrashort period, i.e., a period much shorter than the wavelength of the exciting laser radiation, can form in such a medium. A study is reported of the interaction of light with gratings of this type and of generation of transient signals by these gratings.

A theoretical investigation is reported of the influence of laser fluctuations on the formation of ultrashort-period population-inversion gratings in the case of an inhomogeneously broadened resonant transition. It is shown that such gratings may be formed in a narrow spectral interval and that their amplitude always obeys the normal distribution for different spectral isochromats.
