Dynamics of the transient regime of spaser

The dynamics of the nonradiative excitation of plasmons in the surface plasmon amplifier by stimulated emission of radiation (spaser) that represents a two-level quantum dot in the vicinity of the metal (plasmon) nanoparticle is considered. It is demonstrated that the steady-state generation of spas...

Description
Summary:The dynamics of the nonradiative excitation of plasmons in the surface plasmon amplifier by stimulated emission of radiation (spaser) that represents a two-level quantum dot in the vicinity of the metal (plasmon) nanoparticle is considered. It is demonstrated that the steady-state generation of spaser is preceded by the regime with the oscillations at the Rabi frequency in which the phase difference between the dipole moments and the direction of the energy flux from the quantum dot to the nanoparticle exhibit the sign alternation.
