In the last decade there has been an essential progress in coherent control of a resonant light-matter interaction. One approach is based on excitation of atomic coherence at the atomic transition adjacent to those resonantly coupled with light. Another approach is based on temporal and spatial modulation of the atomic transition frequency under the action of the strong far-off resonant control field via adiabatic Stark or Zeeman effects. I shall review recent progress in this field of research and its extension from gaseous to solid media including both (i) optical electronic and (ii) gamma-ray nuclear transitions.
