Abstract : Under this grant a number of new results were obtained by this principal investigator and his group in the field of nonlinear optics and quantum electronics: (1) Pioneering theoretical research on x-ray nonlinear optics, aimed to diversify coherent x-ray sources by means of nonlinear frequency transformations (mixing of x-ray and optical radiation, stimulated Raman scattering, etc.) (2) Theoretical research on phase-matching optimization of large-scale nonlinear frequency upconversion, with a potential to substantially improve the efficiency of this new source of short wavelength coherent radiation. (3) Theory of high harmonic generation in superdressed two-level atoms. (4) Theory of modulation induced inhibition of dynamics and high order frequency mixing in two-level atoms. (5) Bright-blue 2 pi-solitons in stimulated Raman scattering. (6) Pilot theoretical research on the subfemtosecond soliton formation and propagation, in particular, on subfemtosecond pulses in mode-locked 2 pi-solitons of the cascade stimulated Raman scattering, and the so called electromagnetic bubbles. (7) Experimental research on biological applications of nonlinear laser spectroscopy (two-photon induced fluorescence).
