Generation and detection of high frequency gravitational waves at intensive electromagnetic excitation

The ways of generating and detecting of high frequency gravitational wave in free space and in nonlinear dielectric media under intensive electromagnetic emission excitation have been analyzed. It was shown that there is the opportunity to realize the parametric process of gravitational wave generation with high frequency ω_g = 2ω₀ due to combining of two electromagnetic waves with frequency ω₀. In the dielectric medium synchronism conditions may be reached if the frequency ω₀ of exciting light corresponds to so call unitary polaritons, characterized by unity refraction index. The detection of gravitational waves with frequency ω_g = 2ω₀ may be examined by means of the third harmonic generation registration in corresponding dielectric media.
