Abstract :
Summary form only given. Highly excited Rydberg atoms are very sensitive to static and AC electric and magnetic fields, and can be used for spectroscopic detection and compensation of such fields. We report the use of Rydberg atom spectroscopy to determine the electric field in millimeter-sized, strongly coupled plasmas that are generated by laser excitation of laser-cooled clouds of atoms.
