Transient four-wave mixing signals were observed in cold sodium atoms. This phenomenon is interpreted as Bragg diffraction of a probe pulse by a population grating of the ground-state hyperfine level induced by pump pulses. The decay time of this grating is directly related to the temperature of the cold atoms and can serve as a novel technique for temperature diagnostics.

  12. The ~10-cm mean free path of the Na atom in a MOT is much larger than the cloud size. Also, the effects of the forces of gravity and the ~10-G/cm magnetic-field gradient on atoms in a MOT are both negligible at the time scale of interest.
