We theoretically study the Talbot effect resulting from Raman-induced grating based on periodic spatial
modulation of the Raman gain and dispersion in the field of a standing pump wave. Features of integer and
fractional Talbot effects are demonstrated for one- and two-dimensional (1D and 2D) Raman-induced gratings.
It is shown that the intensity of diffraction images can increase due to Raman amplification in the grating.
Glass-shaped diffraction patterns are demonstrated for 2D gratings. It is also shown that in the vicinity of the
Talbot planes there are planes in which the diffraction patterns are spatially compressed and the intensity becomes
greater. The results expand the possibility of using the Talbot effect in various applications.
