Nonlinear chirooptical effects 

Chirooptical effects are present in media which are chiral: lacking symmetry that makes it possible to superimpose an object on itself after reflection in a mirror plane. The two principal chirooptic effects are the circular birefringence and circular dichroism. They refer to the differences between the refractive index and absorption coefficient, respectively, for circular polrized light of opposite senses.

We have started research on nonlinear optical analogues of the chirooptic effects.

Here are the papers we published on these effects so far:
