Abstract The article presents the results of studies on stability dissipative structures (DS) arising in resonant interaction laser radiation with a nonlinear medium. Resonant is modeled by one dimensional complex Ginzburg-Landau equation nonconservative cubic–quintic nonlinearity. areas existence stable DS solutions have been determined analytically using variational approach and confirmed num...

The present article summarizes the results of a study optical Cherenkov radiation (ChR) spectral properties both theoretically and experimentally. This type has continuous distribution which allows to use it in different fields physics as for charged particle identification or generation intense THz radiation. By exploiting frequency dependency target permittivity is possible observe quasi–mono...

Under proper initial conditions, the interrelated effects of phase and attenuation dispersion in ultrawideband pulse propagation modify the input pulse into precursor fields. Because of their minimal decay in a given dispersive medium, precursor-type pulses possess optimal penetration into that material at the frequency-chirped Lambert-Beer's law limit, making them ideally suited for remote sen...

We experimentally demonstrate diffraction from a straight edge in a medium with self-focusing nonlinearity. Diffraction into the shadow region is suppressed with increasing nonlinearity, but mode coupling leads to excitations and traveling waves on the high-intensity side. Theoretically, we interpret these modulations as spatially dispersive shock waves with negative pressure.

Modeling an anisotropic spatially and temporarily dispersive magnetodielectric medium by two independent collections of three dimensional vector fields, we demonstrate a fully canonical quantization of electromagnetic field in the presence of such a medium. Two tensor fields which couple the electromagnetic field with the medium and have an important role in this quantization method are introdu...
