Laser excitation of the dark bound photonic states during parametric processes in dielectric media

Dispersion laws of darktons (non radiative quasiparticles) in vacuum and in dielectric media were analyzed. The theory of dark bound photonic states generation as the result of different parametric processes is developed. Fermi resonance condition for dark bound photonic states forming is discussed. The experimental setups for dark bound photonic states detection are proposed. The generation of coherent darktons emission by using of powerful pulsed laser as the pumping source for parametric processes excitation in dielectric media is predicted. The synchronism conditions in photon-darkton conversion processes are proved on the base of unitary polaritons (refractive index close to unity) exciting.
