We excite atomic hydrogen from the ground state via a three-photon process to high-lying excited states in the presence of strong d.c. electric fields. The external field is used to manipulate, control, and design specific atomic structures. We can construct nearly `one-dimensional' atoms whose electronic distributions are highly extended along the field, and which may have enormous electric dipole moments ('giant-dipole atoms').
