Paper Abstract

The recent achievements in laser physics, especially progress in generation of intense picosecond and subpicosecond optical, microwave and X-ray pulses, fabrication of new effective nonlinear materials offers the new perspectives in control, diagnostics and modeling of biological processes. of special importance are the applications of the nonlinear optical methods (probably including methods of nonlinear X-ray optics) for these purposes. Nonlinear response has sufficient advantages in comparison with linear one in probing of biological processes. Nonlinear spectroscopy, resonant CARS can be widely used for diagnostics of energy transfer and conformations in biological molecules. The technique of surface optical harmonics and sum frequency generation became a powerful method to study selectively the interfaces of biological interest like the air-water interface, dynamics of chemical reactions at the surfaces and interfaces, etc. Control of the topology and scale of transversal interactions in nonlinear optical resonators leads to exciting possibilities for modeling of nonlinear dynamics of biological processes, like generation of dissipative structures, reverberators, spiral waves, routes to chaos. It was demonstrated that such nonlinear resonators are the optical analogs of neural networks.
