Expected results and their actuality
The research of the Centre involves a large class of basic and applied investigations with the goal of achieving a fundamental understanding of the nonlinear interaction of free charged particle beams and plasma, atoms/ions, and nanostructures with the strong electromagnetic fields - towards the construction of small setup devices such as lasers operating in THz, XUV, and gamma-ray domain of frequencies, as well as compact unconventional accelerators, and at the construction of quantum-information communication networks/computers. Short wavelength coherent sources may offer significant advantages in applications like holograms of microscopic biological structures, as well as in many fields where coherent, short wavelength radiation is required like holography and interferometry on a sub-micrometer scale etc. The next generation of particle accelerators will likely depend upon novel schemes of reaching the high energies necessary for exploring the future frontiers of physics. Laser acceleration is the main candidate for the solution of this challenging problem, besides it will have significant applications especially in medicine and Hi-Tech industry. Besides, it is expected the efficient contribution of planned experimental investigations in laser biomedicine, with the implementation of laser synthesis of colloidal nano-particles of diverse physicochemical properties and nonlinear laser spectroscopic methods in nano-bio-medicine.
