Coherent responses of resonance atom layer to short optical pulse excitation

摘要

Coherent responses of resonance atom layer to short optical pulse excitation are numerically considered. The inhomo-geneous broadening of one-photon transition, the near dipole-dipole interaction, and the substrate dispersion are involved in analysis. Under certain intensity of incident pulses, a strong coherent interaction in the form of sharp spikes of superradiation is observed in transmitted radiation. The Lorentz field correction and the substrate dispersion weaken the effect, providing additional spectral shifts. Specific features of photon echo in the form of multiple echoes to a double or triple pulse excitation in the presence of near dipole-dipole interaction is discussed.
