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.
