Extremely strong fields and ultrashort optical pulses
Effect of particle concentration on the dynamics of microcavities during the collision of 2$\pi$-like unipolar pulses of self-induced transparency in a three-level medium
Abstract:
Based on the numerical solution of the system of material equations for the density matrix together with the wave equation for the electric field strength, the effect of the particle concentration of a three-level medium on the dynamics of microcavities during the collision of 2$\pi$-like unipolar attosecond pulses of self-induced transparency in a three-level medium is studied. The effect of changing the temporal shape of the pulses during propagation in a dense medium on the shape of the microcavities is also studied. It is shown that with increasing particle concentration the formation of microresonators is preserved, but their shape can be distorted.
Keywords:extremely short pulses, attosecond pulses, dynamic microcavities.
