Optimization of the light-induced-fluorescence signals of single atoms and efficient loading of single atoms into a magneto-optical trap

Jieying Wang, Bei Liu, Diao Wen-Ting +3 more

In our experiment, firstly, we carry out the loading of single atoms in the magneto-optical trap (MOT) by increasing the quadrupole magnetic field gradient, improving the background vacuum, and reducing the diameters of the cooling and trapping laser beams. Secondly, we get the single atomic fluorescence signal of a high signal-to-background ratio in the MOT by means of reducing the detuning of cooling light and increasing its intensity appropriately, and using the polarization spectroscopy locking technique to suppress the fluctuations of cooling laser. In addition, with the real-time feedback on quadrupole magnetic field gradient, we demonstrate a probability of loading single atoms in the MOT as high as 98%. We also measure the statistical properties of the single atomic fluorescence which is excited by continuous light in the MOT; the measured second-order correlation is g(2)( = 0) = 0.09.

Detection of atoms in a beam: filtering of the atomic shot noise and velocity dispersion contribution

N. Dimarcq, C. Audoin

We calculate the contribution of the atomic shot noise in the detection of the laser-induced fluorescence signal emitted by atoms in a beam. We point out a filtering of such a contribution which is the consequence of the finite transit time of the atoms through the laser beam. Moreover, we demonstrate that the distribution of the atomic velocities in the beam induces an extra noise which degrades the measured signal-to-noise ratio and modifies the observed statistics of the fluorescence photons emitted by the whole interaction zone.

Detection of cavity fields by means of quantum-jump statistics

Jan Grochmalicki, Maciej Lewenstein

We consider a single three-level atom placed inside a resonant cavity and simultaneously probed in a double-resonance ladder configuration by a relatively strong laser beam. It is shown that photocounting statistics of a fluorescence signal induced by the probe, in certain circumstances, exhibits dark periods (i.e., quantum jumps are present), reflecting the statistical properties of the field inside the cavity. Comparisons are made between the number, thermal, coherent, and squeezed states. Specific features of the latter are pointed out.
