We propose a laser cooling scheme that allows to cool a single atom
confined in a harmonic potential to the trap ground state 
.
The scheme assumes strong confinement, where the oscillation frequency
in the trap is larger than the effective spontaneous decay width, but is
not restricted to the Lamb-Dicke limit, i.e. the size of the trap
ground state can be larger than the optical wavelength. This cooling
scheme may be useful in the context of quantum computations with ions
and Bose-Einstein condensation.
