  We report laser cooling of fermionic K-40 atoms, with temperatures down to
(15 +/- 5) microK, for an enriched sample trapped in a MOT and additionaly
cooled in optical molasses. This temperature is a factor of 10 below the
Doppler-cooling limit and corresponds to an rms velocity within a factor of two
of the lowest realizable rms velocity (~3.5v rec) in 3D optical molasses.
Realization of such low atom temperatures, up to now only accessible with
evaporative cooling techniques, is an important precursor to producing a
degenerate Fermi gas of K-40 atoms.
