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...

A Bäcklund transformation(BT) and a recurrence formula are derived by the homogeneous balance(HB) method. A initial problem of Burgers equations is reduced to a initial problem of heat equation by the BT, the initial problem of heat equation is resolved by the Fourier transformation method, substituting various solutions of the initial problem of the heat equation will yield solutions of the in...
