“…In the middle of 70 s the first experimental evidence of the nonlinear optical activity [4] came to light, giving the impulse to the development of the corresponding phenomenological theory [5][6][7][8][9].

“…However, all results of [5][6][7][8][9] were obtained within the framework of slowly varying envelope approximation (SVEA), which is not suitable for the description of ultrashort pulses. In this case the evolution of the electric field strength vector can be described in terms of the changes of its modulus and orientation in space.…”

We propose a general model of third-order nonlinear optical susceptibility of isotropic gyrotropic medium with frequency and spatial dispersion. Our model allows for the description of the propagation of ultrashort (several oscillations) elliptically polarized laser pulses in such a medium and does not require smallness of the characteristic nonlocality dimension, unlike the conventional phenomenological model. We implemented our model numerically by means of a modified finite-difference time-domain method with an auxiliary differential equation. We have validated the correctness of our model by the comparison of the results obtained in our numerical simulations with generally known effects observed experimentally and described earlier theoretically for the monochromatic radiation or within the slowly varying envelope approach. We investigated effects accompanying the propagation of ultrashort (several oscillations) light pulses in nonlinear isotropic gyrotropic medium with frequency and spatial dispersion of cubic nonlinearity.

The interest in nonlinear liqht reflection phenomena is caused by the fact that they can give a unique information about crystals' surface propertiesIn this work we have used the boundary conditions on the surface of nonlinear media with space dispersion (SD) obtained in " . We have considered phenomenologically polarization effects due to interaction of the two arbitrarily polarized waves durinq both propagation and reflection from crystals of cubic, hexagonal and tetraqonal crystal systems (the incident angles of light are supposed equal to zero, and the crystal optical axis to be perpendicular to the boundary). 10 both cases for media with weak gyrotropy four mechanisms of nonlinear optical rotation (NLOR) and deformation (NLOD) of polarization ellipses have been determined. It has been made )fl a first approximation with respect to the parameter of SD Jd/.(here ci is a characteristic length of spatial non-locality ot response, ?*, is a wavelength). The influence of linear qyrotrop>' and dissipation on the interaction ha also been investigated. A nonlinear polarization spectroscopy scheme has been suggested. This scheme allows one to distinqush between contributions of different NLtJR and ILOD rnechansms irrespective of the crystal symmetry. The study of NLOR and NLOD effects during the interaction of two elliptically poirized waves with the medium is shown to give three or four as much spectroscopy information on the cubic nonlinearity and )ts SD as in the case of application of a plane-polarized wave. Moreover the joint study of liqht polarization interaction during both reflection and propagation of waves through the crystal is most effective. This is connected with the fact that spectroscopy information received in experiments 'on reflection' and 'on propagation' is complementary to a great degree 2.

Applying boundary conditions on the surface of nonlinear media with SD (see forcnulcie (5),(7) in ) to the case of two--wave interaction we obtain (at z=O):
