We excite the atoms using a Doppler-free two-photon transition from the $6s\\,^2S_{1/2}$ ground state, and detect the 1.47$\\mu$m photons from the spontaneous decay of the $7s\\,^2S_{1/2}$ to the $6p\\,^2P_{3/2}$ state. We use a gated single photon detector in an asynchronous mode, allowing us to capture the fluorescence profile for a window much larger than the detector gate length.
