Ramsey interferometry with an atom laser.
We present results on a free-space atom interferometer operating on the first order magnetically insensitive |F = 1,mF = 0) --> |F = 2,mF = 0) ground state transition of Bose-condensed (87)Rb atoms. A pulsed atom laser is output-coupled from a Bose-Einstein condensate and propagates through a sequence of two internal state beam splitters, realized via coherent Raman transitions between the two ...
متن کاملSingle Atom and Two Atom Ramsey Interferometry with Quantized Fields
Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this case it is shown how an analog of Hanbury-Brown Twiss photon-photon correlation interferometry can be used to discern a variety of interferenc...
متن کاملTowards the Quantum Noise Limit in Ramsey-Bordé Atom Interferometry
In this work, the relevant noise sources in atom interferometers of Ramsey-Bordé type were investigated, which are the noise of the excitation induced by the interrogation and the noise of the detection of the excitation. In the first part of the work, the methods for the considerable reduction of the frequency noise of the interrogation laser in the low and in the high frequency range are desc...
متن کاملRamsey Interferometry with Quantized Fields
Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this case we show how two atom (like two photon) interferometry can be used to discern a variety of interference effects as the two independent Ram...
متن کاملAtom Interferometry with Mechanical Structures
We present results on an interferometer for atoms based on Young's double-slit experiment. We also discuss proposed experiments in which the effect of spontaneous emission on the visibility of the atomic fringe pattern, as well as the effect of coherent atom-light interactions on the phase of the atomic wavefunction could be measured.
