The talk consists of two parts. In the first, we have demonstrated enhancement of nonlinear signals
and suggested a new approach that extends Raman spectroscopy to media which has a high level of
scattering. The stimulated Raman scattering has an advantage of relaxing phase-matching condition
which is difficult or even impossible to meet under condition of strong scattering. The second topic is
related to enhanced optico-mechanical coupling that occurs when the group velocity of light is ultra-slow.
We show theoretically that, due to dragging of the light by the mechanical motion of the medium, it is
possible to control phase-matching condition.
