Abstract

The use of light presure to cool and stop neutral atoms has been an area of considerable interest recently. Cooled neutral atoms are needed for a variety of interesting experiments involving neutral atom traps and ultrahigh-resolution spectroscopy. Laser cooling of sodium has previously been demonstrated using elegant but quite elaborate apparatus.^1,2 These techniques employed stabilized dye lasers and a variety of additional sophisticated hardware. We have demonstrated that the frequency chirp technique of Ref. 2 can be implemented using inexpensive diode lasers and simple electronics.
