A Treatment of the Absorption Spectrum for a MultiphotonV-TypeThree-Level Atom Interacting with a Squeezed Coherent Field in thePresence of Nonlinearities

摘要

We study the interaction of a three-level atom with a single mode fieldthrough multiphoton transition in a cavity, taking explicitly into account theexistence of forms of nonlinearities of both the field and the intensity-dependentatom-field coupling. The analytical forms of the absorption spectrum is calculatedusing the dressed states of the system. The effects of photon multiplicities, meanphoton number, detuning, Kerr-like medium, and the intensity-dependent couplingfunctional on the absorption spectrum are analyzed.
