The classic examples of optical phenomena resulting in the appearance of solitons are self-
focusing, self-induced transparency, and parametric three-wave interaction. To date, the list …

For electromagnetic pulses without a carrier frequency, propagating in a system of multilevel
atoms with a fast irreversible relaxation of the induced dipole moment, but a slow relaxation …

Our recent studies of methods for obtaining ultrashort light pulses and analysis of the impact
of ultrashort optical pulses on classical and quantum micro-objects with the identification of …

Specific features of the transportation of extremely short radiation pulses in a metal
waveguide are analyzed. It is inferred that the mode dispersion can be suppressed, thereby …

The possibility of the formation of metastable unipolar soliton-like electromagnetic objects in
nonequilibrium dissipative media has been predicted. It has been shown that these objects …

The generalized sine-Gordon equation is obtained under the theoretical investigation of
interaction of few-cycle pulses in a nonlinear medium modeled by a set of four-level atoms …

In the regime of resonant coherent light–matter interaction, light pulses may interact with
each other indirectly via a polarization wave created by the other pulse. We show that such …

We suggest a method to derive the nonlinear wave equations suitable for describing the
propagation of light pulses as short as two optical cycles in transparent nonlinear optical …

A short scientific-methodological review of theoretical studies and approaches created in the
field of nonlinear optics of ultimately short pulses in the period from 1970s up to now is …

A Hamiltonian framework is developed for a sequence of ultrashort optical pulses
propagating in a nonlinear dispersive medium. To this end a second-order nonlinear wave …
