Second harmonic generation by light-wave-plasma interaction in oscillating magnetic field

The nonlinear generation of second harmonic electromagnetic wave from a thin inhomogeneous (dense and rarefied) plasma layer (of width d) by obliquely and normal incidence of light wave is analyzed. We consider the effect of external time-dependent magnetic field on the generation and amplification of waves. Two cases are considered; when the external magnetic field oscillates at frequency (i) equal, and (ii) double the frequency of the incident wave.
