Qed stimulated emission
WebMar 14, 2024 · We investigate the stimulated emission of superradiant atoms coupled to a waveguide induced by a coherent-state photon pulse. We provide an analytical result when a short $π$ pulse is incident, which shows that the atoms emit photons coherently into the output pulse, which remains a coherent state in the short pulse limit. An incident pulse is … WebMar 16, 2016 · Title: Cutting Feynman Loops in Ultrastrong Cavity QED: Stimulated Emission and Reabsorption of Virtual Particles Dressing a Physical Excitation.

WebFeb 25, 2008 · To characterize the amplification (stimulated emission) of an active medium, we launch a probe signal into the system. With the presence of a pumping signal, population inversion takes place within the active medium. As a result, the probe signal is amplified during propagation through the medium.

WebWe introduce a novel approach to study the gain and dynamics of a terahertz (THz) QCL [7] using phase resolved measurements of the stimulated emission. This is enabled by direct recording of the emitted electric field with 100 fs time resolution. For the case of the THz QCL we demonstrate the validity of the quantum mechanical description of ...
