Dynamics of microresonators induced by extremely short pulses in a three-level medium

Based on the numerical solution of the system of equations for the density matrix together with the wave equation for the electric field strength, the dynamics of atomic populations and polarization of the medium during collisions of unipolar extremely short pulses of half-cycle pulses in a three-level medium is studied. The possibility of ultrafast switching of the state of the medium and the possibility of guiding optical microresonators at each resonant transition of the medium are shown. The considered multilevel system is an example of a non-stationary spatially inhomogeneous medium, the optical characteristics of which quickly change both in space and in time under the action of extremely short pulses.
