Self‐induced diffraction of ultrashort pulses in silicon crystals at high incident light intensities is studied. A theoretical model is presented which takes into account the band‐filling effect as a major mechanism of light‐induced grating anharmonicity. Experimental results on the energetic and temporal characteristics of four orders of diffraction are in good agreement with this theoretical model.
