Fractional dynamical diffraction Talbot effect for a cosine-like grating. (a) The intensity distribution in free space at the distance zT/4. (b) The intensity distribution inside the crystal at the depth zTd/4 calculated by the exact formula (5)[link] (curve 1, blue) and by the approximate formula (46)[link] (curve 2, green). (c) The intensities of the weakly absorbing (curve 1, blue) and strongly absorbing modes (curve 2, green) calculated by the exact formula (5)[link] at the depth zTd/4.
