Abstract

We have demonstrated nondestructive detection of cold atoms with a probe laser by a frequency-modulation spectroscopy technique. We were able to tune the probe laser and its sidebands far from atomic resonance to reduce the spontaneous emission to less than 0.2 photon per atom during detection.

Optimal strategies for low-noise detection of atoms using resonant frequency modulation spectroscopy in cold-atom interferometers

Ryan Thomas, Samuel Legge, Simon A. Haine +1 more

Resonant frequency modulation spectroscopy has been previously used as a highly sensitive method for measuring the output of cold atom interferometers. Using a detailed model that accounts for optical saturation, laser intensities and atomic densities that vary spatially, and radiation pressure on the atoms, we theoretically investigate under what parameter regimes the optimum signal-to-noise ratio is found under experimentally realistic conditions. We compare this technique to the standard method of fluorescence imaging and find that it outperforms fluorescence imaging for compact interferometers using condensed atomic sources or where the photon collection efficiency is limited. However, we find that fluorescence imaging is likely to be the preferred method when using squeezed atomic sources due to limited atom number.

Limit to Minimally Destructive Optical Detection of Atoms

J. J. Hope, J. D. Close

All optical techniques used to probe the properties of Bose-Einstein condensates have been based on dispersion and absorption that can be described by a two-level atom. Both phenomena lead to spontaneous emission that is destructive at the low energies involved with ultracold atomic systems. Recently, both were shown to lead to the same limit to the signal to noise ratio for a given destruction. We develop a new method for calculating the phase shift of a laser beam and show that no single-pass optical technique using classical light and a three-level atom can exceed this limit. This puts significant restrictions on potential nondestructive measurement schemes.

Surface-plasmon-based dispersive detection and spectroscopy of ultracold atoms

Matthias Mildner, Claus Zimmermann, Sebastian Slama

The paper reports on the optical detection and spectroscopy of ultracold atoms near a gold surface.A probe light field is used to excite surface plasmon polaritons.The refractive index of the atomic gas shifts the plasmon resonance and changes the reflected light power.Thus, the sensitivity of the detection is plasmonically enhanced.Absorption of photons from the evanescent wave is avoided by detuning the laser from atomic resonance which makes the detection scheme potentially nondestructive.The spectrum of the signal is determined by a Fano resonance.We show that atoms can be detected nondestructively with single atom resolution for typical parameters in cold atom experiments.Thus, the method is suitable for quantum nondemolition measurements of matter wave amplitudes.Experimentally, we measure a technically limited sensitivity of 30 atoms and extend the detection scheme to dispersively image the atom cloud near the surface.

Low-noise detection of ultracold atoms

J. M. McGuirk, G. T. Foster, J. B. Fixler +1 more

We have demonstrated a new technique for detecting ultracold atoms. A balanced detection technique was used to reduce laser-induced detection noise in conjunction with modulation-transfer spectroscopy to distinguish cold atoms from a thermal cloud. Using this technique, we have achieved signal-to-noise ratios in excess of 2000:1.

General limit to nondestructive optical detection of atoms

J. J. Hope, J. D. Close

We demonstrate that there is a fundamental limit to the sensitivity of phase-based detection of atoms with light for a given maximum level of allowable spontaneous emission. This is a generalization of previous results for two- and three-level atoms. The limit is due to an upper bound on the phase shift that can be imparted on a laser beam for a given excited-state population. Specifically, we show that no single-pass optical technique using classical light, based on any number of lasers or coherences between any number of levels, can exceed the limit imposed by the two-level atom. This puts significant restrictions on potential nondestructive optical measurement schemes.
