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. |
