Object of study: atoms and particles of submicron size (nanoparticles) in coherent optical fields. Methods of investigation: theoretical methods for the analysis of processes of the resonant interaction of laser radiation with matter, spectroscopic methods of investigation, the method of holographic photopolymerization, computer simulation. We propose an intuitive picture of the optical rangefinder with frequency-shifted feedback laser. A fully fiber-optic ring frequency shifted feedback laser with Er3+ is created. The proposed method of implementation of a large radiation pressure on atoms and optical trap for atoms created by counterpropagating sequences of light pulses are theoretically studied. Some aspects of the theory of stimulated Raman adiabatic passage and the mechanical analog of rapid adiabatic passage in atomic physics, the formation of coherent population trapping resonance in bichromatic and polychromatic fields are discussed. Proposed and justified a new method of storage of the coherence of atomic states in the populations. The diffractive optical elements based on photopolymer nanocomposites were manufactured by holographic method and investigated. The matched filtering of recognizable objects represented as phase masks were investigated. A source of spatially coherent femtosecond supercontinuum with controllable output parameters was created and was usedfor investigation of the photorefractive lithium niobate crystal.
