Conditions for trapping sodium atoms in far detuned dipole traps are explored with the goal of maximizing phase space density and coherence times. With red detuned traps, we have been able to achieve densities as high as 2 ×1012atoms/cm3 at temperatures on the order of (11ħk)2/2M. We also report Raman cooling in a red de‐tuned trap to a one dimensional “temperature” of 0.7(ħk)2/2M. With a blue detuned trap, we have been able to observe Ramsey interference fringes between the ground states of sodium for over 4 seconds. Finally, we report an atom interferometer based on adiabatic transfer of ground state populations.
