Observation of atomic localization using Electromagnetically Induced Transparency
We present a proof-of-principle experiment in which the population of an atomic level is spatially localized using the technique of electromagnetically-induced transparency (EIT). The key idea is to utilize the sensitive dependence of the dark state of EIT on the intensity of the coupling laser beam. By using a sinusoidal intensity variation (standing-wave), we demonstrate that the population o...
متن کاملSubwavelength Localization of Atomic Excitation Using Electromagnetically Induced Transparency
We report an experiment in which an atomic excitation is localized to a spatial width that is a factor of 8 smaller than the wavelength of the incident light. The experiment utilizes the sensitivity of the dark state of electromagnetically induced transparency (EIT) to the intensity of the coupling laser beam. A standing-wave coupling laser with a sinusoidally varying intensity yields tightly c...
متن کاملLocalization of Atomic Excitation beyond the Diffraction Limit Using Electromagnetically Induced Transparency
We experimentally demonstrate the localization of excitation between hyperfine ground states of 87Rb atoms to as small as λ/13 wide spatial regions. We use ultracold atoms trapped in a dipole trap and utilize electromagnetically induced transparency (EIT) for the atomic excitation. The localization is achieved by combining a spatially varying coupling laser (standing-wave) with the intensity de...
متن کاملElectromagnetically Induced Transparency in 6 Li Electromagnetically Induced Transparency In
We report electromagnetically induced transparency for the D1 and D2 lines in 6 Li in both a vapour cell and an atomic beam. Electromagnetically induced transparency is created using co-propagating mutually coherent laser beams with a frequency difference equal to the hyperfine ground state splitting of 228.2 MHz. The effects of various optical polarization configurations and applied magnetic f...
متن کاملDecoherence of electromagnetically induced transparency in atomic vapor.
We report characterization of electromagnetically induced transparency (EIT) resonances in the D1 line of (87)Rb under various experimental conditions. The dependence of the EIT linewidth on the power of the pump field was investigated at various temperatures for the ground states of the lambda system associated with different hyperfine levels of the atomic 5S(1/2) state as well as magnetic sub...
