Abstract : Under AFOSR grant F49620-93-1-0220, 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 super-dressed two-level atoms; (4) Theory of modulation-induced inhibition of dynamics and high-order frequency mixing in two-level atoms; (5) Bright-bright 2pi-solitons in stimulated Raman scattering; (6) Pilot theoretical research on the subfemtosecond soliton formation and propagation, in particular, on subfemtosecond pulses in mode-locked 2pi-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); and (8) Other research: eigenmodes of X(2) wave-mixings and X-ray narrow-line transition radiation source based on low-energy electron beams traversing a multilayer nanostructure.
