Abstract

We shell investigate the propagation dynamics of optical pulses in media with non stationary optical and magnetic response. We derived a new amplitude integro-differential equation describing their propagation in transparency region of such media. The applied method of the slowly varying amplitude approximation to this equation reduces it to nonlinear Slowly Varying Equation of Amplitudes (SVEA) in second approximation of linear dispersion and in first approximation to the nonlinear dispersion (SVEA). It is important to point out, that the obtained SVEA in media with no stationary optical and magnetic response is similar to the SVEA equation with stationary magnetic response. The only difference is the expression for group velocity and dispersion parameters. Partially, in paramagnetic media near to magnetic resonances it is possible to reach group velocity higher than velocity of light in vacuum.
