Quantum jump spectroscopy of a single neutral atom for precise subwavelength intensity measurements
We present precise, subwavelength optical intensity measurements using a single trapped ^{87}Rb atom as a sensor. The intensity is measured by the scalar ac Stark shift it produces on the F=1→F^{′}=2 hyperfine transition of the D_{2} line, chosen for its F^{′}=F+1 structure and very small tensor pol...
