Breather-like pulses in a medium with the permanent dipole moment

The solutions of the reduced Maxwell-Bloch equations for an anisotropic two-level medium, which describe the propagation of electromagnetic pulses having a duration from a few field oscillations, are studied. An influence of the permanent dipole moment of the quantum transition on dynamics of the pulses and their spectrum is considered.Comment: LaTeX, 9 pages, 6 figure

Optical Solitons in an Anisotropic Medium with Arbitrary Dipole Moments

We find the Lax pair for a system of reduced Maxwell-Bloch equations that describes the propagation of two-component extremely short electromagnetic pulses through the medium containing two-level quantum particles with arbitrary dipole moments.Comment: 5 pages, International Conference on Coherent and Nonlinear Optics (ICONO 2007

Direct method for solving transfer equation by expansion in spherical harmonics: Scattering in atmosphere with Lambertian lower boundary and thermal radiation transfer

The direct method for the solution of the spherical harmonics approximation to the equation of transfer of radiation is applied to the cases of (1) scattering of the solar radiation in the atmosphere with the Lambertian boundary and (2) thermal radiation transfer

Dynamics of two-component electromagnetic and acoustic extremely short pulses

The distinctive features of passing the two-component extremely short pulses through the nonlinear media are discussed. The equations considered describe the propagation in the two-level anisotropic medium of the electromagnetic pulses consisting of ordinary and extraordinary components and an evolution of the transverse-longitudinal acoustic pulses in a crystal containing the paramagnetic impurities with effective spin S=1/2. The solutions decreasing exponentially and algebraically are studied.Comment: LaTeX, 11 pages, 6 figure
