Dataset for Velocimetry of cold atoms by matter-wave interferometry
Paper relates to the measurement of the velocity distribution of atoms within a laser-cooled sample by the means of atom interferometry, by employing an asymmetric Mach-Zehnder interferometer. Data are attached for interferometer output used in 3 velocity profile measurements, with corresponding Raman Doppler spectroscopic measurements of the profiles for comparison. The first column of each data file is the parameter varied, either the temporal asymmetry of the interferometer (in ns) for the interferometer data, or the laser detuning (in kHz) for the spectroscopic measurements. The "output" columns are measurements of the fraction of atoms in the upper energy state. If multiple data are taken for a single point, more that one "output" column is present and additional columns are included for the mean and standard deviation. When there is only one output column, the uncertainty in the measurement of the excited state population is given. Data files with the "doppler-" prefix are the spectroscopic measurements, while each interferometer measurement has two data files taken with ("-inphase" suffix) and without ("-quadrature" suffix) a pi/2 phase shift prior to the final interferometer pulse. The numerical suffix links spectroscopic and interferometric measurements taken under the same conditions.

Abstract

Paper relates to the measurement of the velocity distribution of atoms within a laser-cooled sample by the means of atom interferometry, by employing an asymmetric Mach-Zehnder interferometer. Data are attached for interferometer output used in 3 velocity profile measurements, with corresponding Raman Doppler spectroscopic measurements of the profiles for comparison. The first column of each data file is the parameter varied, either the temporal asymmetry of the interferometer (in ns) for the interferometer data, or the laser detuning (in kHz) for the spectroscopic measurements. The "output" columns are measurements of the fraction of atoms in the upper energy state. If multiple data are taken for a single point, more that one "output" column is present and additional columns are included for the mean and standard deviation. When there is only one output column, the uncertainty in the measurement of the excited state population is given. Data files with the "doppler-" prefix are the spectroscopic measurements, while each interferometer measurement has two data files taken with ("-inphase" suffix) and without ("-quadrature" suffix) a pi/2 phase shift prior to the final interferometer pulse. The numerical suffix links spectroscopic and interferometric measurements taken under the same conditions.
