Experimental observation of a five-wave nonlinear optical process in an optically active liquid: a second-harmonic generation which is sensitive to the mirror asymmetry of biomolecules
Dubrovskii A. V., Koroteev N. I., Shkurinov A. P.
The generation of a noncollinear second harmonic in the five-wave process 2ω = ω+ω + ω — ω in an optically active liquid has been studied experimentally. An estimate |^(4ii>| slO-23 esu is found for an /-arabinose solution. Some new spectroscopic schemes based on measurements of the fourth-order nonlinear susceptibility xw D are analyzed for the case of isotropic media lacking an inversion center.
