The nonlinear interaction between laser and bio-molecule has been studied by the theory of molecular nonlinear polarization. The expressions of operators of Hamiltonian, the moment of dipole and the electric susceptibility with different orders have been evaluated. The contributions of electrons and nuclei to the molecular polarization have been analyzed. A SHG tomography induced by third-order nonlinear optical effect has also been proposed.

Nonlinear Optical Effect

In order to investigate the doping effect of Ba 2 NaNb 5 O 15 by rare-earth ions, single crystals of stoichiometric BNN, Gd-doped BNN, and Nd-doped BNN were synthesized. The measurements were carried out for second harmonic generation (SHG), microscopic observation on {001}, and for dielectric property of these materials. The considerable effects by the doping were found for the SHG. The doping effect was investigated from the point of view of the theory of electro-optical and nonlinear optical effect on oxygen octahedral ferroelectrics, and from that of domain structure. Microscopic observation proved that the refractive index fluctuation causes several SHG phase matching conditions.

The D4σ-Z-scan technique is used to evaluate the sign and the magnitude of the nonlinear (NL) refractive index and the NL absorption (NLA) coefficient with a laser delivering single pulses in the picosecond regime at 355 nm, 532 nm and 1064 nm. The NL optical response of the zinc porphyrins (Pph) has been found to be significantly enhanced. The study of the NLA and refraction is performed, taking into account the time dependence and the spectral width of the incident laser. The variations of the NL coefficients as a function of the intensity and the concentration are provided and are found to be linear.
