Second harmonic hyper-Rayleigh light scattering (HRS)‎ in organic materials

الملخص EN

In this paper, an optical setup to produce harmonic hyper-Rayleigh light scattering (HRS) from organic molecules in solution has been built up.

In principle, HRS measures contribution coefficients of dipole and octupole parts.

The nonlinear susceptibility of the second order of six organic molecules in solution from different chemical components such as Pyridinium, Quinolinium groups and organic Borone complexes has been determined.

The nonlinear susceptibility measurements help to discover and select the most efficient molecules which can be used later as polymer matrices.
