The research progressed basically in these directions: Pilot theoretical research on X-ray nonlinear optics, including resonant saturation related effects in plasmas (nonlinear absorption and nonlinear refractive index), and proposals for X-ray third harmonics generation, X-ray laser with noncoherent pumping, and X-ray four-wave mixing; Experimental discovery and experimental and theoretical research on dark spatial solitons; Theoretical investigation of previously discovered by this PI and his group dispersion related multimode amplification, instabilities, oscillations and chaos in nonlinear counterpropagating waves; Theoretical research on the fundamental problem of gradient-field-induced second-order nonlinear optical processing vacuum due to the photon-photon scattering of intense laser radiation in a dc magnetic field. jg p.4. 收起
