Additional Sidebands in Time Dependent Spectra for a Spacially Distributed Collection of Two-Level Atoms Driven by a Resonant Coherent Field

摘要

We derive the time-dependent spectra of a laser-driven, interacting, collection of spacially distributed two-level atoms. We assume a system with dimensions large relative to a wavelength which is initially in the atomic and electromagnetic field ground state and at the initial time begins to interact with the coherent, externally applied radiation field. The explicit spacial distribution of the two-level atoms affects the time-dependent spectra of the transmitted radiation and the many-body interaction leads to the appearance of additional sidebands.
