We demonstrated the results of investigations on the creation of the new high-precision laser methods and technologies of the on-line detection and operative quantitative analysis of the small and super-small concentrations of sugar, glucose, fructose and other matters dissolved in the transparent liquids based upon the effect of the natural optical activity of such matters. The record- breaking improvement has been achieved of the sensitivity of the registration systems as well as measurement precision in determination of small rotation angles of the radiation polarization plane due to the natural optical activity of solutions.
The model of the pulse laser nephelometry polarization methods of using in biotechnologies and ecology is elaborated. It is shown that informativity of the laser nephelometry measurements increases when polarization self- action effects of short pulses of the laser radiation are taken into account by multiple scattering is dispersed biological media with high concentration of weighted particles. The soliton and simulton regimes of the polarization transformation of the laser pulses have been investigated. Conditions of the modulation instability are determined of the pulse laser radiation of arbitrary polarization in nonlinear scattering biomedia.
The results on the modeling of non-linear dynamics of strong continuous and impulse radiation in the laser nephelometry of polydisperse biological systems, important from the viewpoint of applications in biotechnologies, are presented. The processes of nonlinear self-action of the laser radiation by the multiple scattering in the disperse biological agro-media are considered. The simplified algorithms of the calculation of the parameters of the biological media under investigation are indicated and the estimates of the errors of the laser-nephelometric measurements are given. The universal high-informative optical analyzers and the standard etalon specimens of agro- objects make the technological foundation of the considered methods and systems.
Nonlinear magneto-optical resonances of the heterogeneous transfer of the charge between atoms, which resonantly interact with the laser radiation, and the surface of the metal or the semiconductor are investigated. The dependence of nonlinear magneto-optical resonances of the surface photoionization of atoms on the values of the angular moment of the energetic levels is analyzed. The possibility of the splitting of the surface photoionization resonance in magnetic field is found.
The dependence of nonlinear resonances of two-photon scattering on acoustic vibrations in gases is investigated on the polarization of the laser radiation, the angular moment of the energetic levels and magnetic field.
In the present paper we analyze the results of our experimental investigations of nonlinear dynamics of the free generation of the ions of chromium and neodymium in the various media. The results of the theoretical investigations of the role of the dynamic Stark effect and stochastic factors are produced in the generation forming.
