General information

Name of the project: Quantum effects in strongly localized intense laser fields

Strategy for Scientific and Technological Development Priority Level: а

Goals and objectives

Research directions: Quantum optics, nonlinear optics, interactions of ultra-intense laser fields

Project objective: Developing new methods for creating marginally localized structures of electromagnetic fields and research of classical and quantum effects in interaction of matter and quantum vacuum with such structures, as well as development of elements of devices for quantum information technologies that use strong field localization.

The practical value of the study

  • Novel methods for increasing the peak and average power of laser systems based on multicore optical fibers, spatial light modulators, and coherent beam combining were developed. An efficient method of coherent combining of many optical emitters easily scalable for an unlimited number of channels has been proposed and experimentally verified. Studies of laser beam propagation and amplification regimes in multicore fibers, which are stable at high power and allow dramatic scaling of the peak power of laser systems, were carried out. The possibilities of creating highly localized field structures with controlled parameters in the systems utilizing spatial light modulators and multicore fibers were investigated. A theoretical study of quantum properties of coherent laser beam combining was carried out. The standard quantum noise limit for radiation resulting from coherent combination with a feedback system was found.

  • Using supercomputer simulation, the interaction of high-power radiation with the quantum vacuum in the presence of a seed plasma target, namely the development of an electron-positron cascade in the field of laser beams focused in the form of electro- or magnetic-dipole waves, has been investigated. The stability of the investigated regimes against imperfections of the dipole wave synthesis was proven, which gives grounds for the possibility of observing the electron-positron cascade in multi-petawatt laser systems currently being designed. New regimes of interaction of high-power laser radiation with electron-positron plasma leading to the formation of highly localized laser-plasma structures have been discovered.

  • The features of the interaction of quantized radiation with matter are investigated under conditions of strong localization of the field and/or interacting particles in various systems. In particular, a theory of photon emission by a nonequilibrium open quantum system in the regime of Purcell amplification in a sub-wavelength quasi-two-dimensional cavity was developed; a systematic theoretical study of bulk and surface polaritons in Weyl semimetals with broken time-reversal symmetry was carried out; and a theoretical model of electron-hole pairs generation by a powerful terahertz pulse in graphene was developed. The theory made it possible to quantitatively explain the results of experiments on nonlinear nano-scale diagnostics of graphene using a nanoprobe illuminated by ultrashort laser pulses. The features of the interaction of X-ray and UV photons with an oscillating absorber, leading to acoustically-induced transparency and the formation of a sequence of attosecond pulses, were investigated. The possibility of the formation of quantum-squeezed light in highly nonlinear chalcogenide optical fibers was shown theoretically for the first time.

  • An advanced setup was created for manufacturing and experimental study of the properties of microresonators based on silica and special soft glasses. Various scenarios of the generation of optical frequency combs in silica microspheres, as well as novel methods of exciting Raman generation in chalcogenide microspheres, were demonstrated experimentally. Numerical models of nonlinear and thermo-optical effects in microresonators were developed, the results of which were verified experimentally.

Education and career development:
