Absolute frequency measurement of rubidium 5S-6P transitions
Conny Glaser, Florian Karlewski, Jens Grimmel +4
We report on measurements on the 5S-6P rubidium transition frequencies for rubidium isotopes with an absolute uncertainty of better than \SI{450}{kHz} for the 5S 6P$_…
Observation of the motional Stark shift in low magnetic fields
Manuel Kaiser, Jens Grimmel, Lara Torralbo-Campo +5
We report on the observation of the motional Stark effect of highly excited Rb Rydberg atoms moving in the presence of a weak homogeneous magnetic field in a vapor cell. Emp…
Ionization spectra of highly Stark shifted rubidium Rydberg states
Jens Grimmel, Markus Stecker, Manuel Kaiser +4
We report on the observation and numerical calculation of ionization spectra of highly Stark-shifted Rydberg states of rubidium beyond the classical ionization threshold. In the nu…
All-optical measurement of Rydberg state lifetimes
Markus Mack, Jens Grimmel, Florian Karlewski +3
We have developed an all-optical method for measuring the lifetimes of and Rydberg states and demonstrate its capabilities with measurements on a dilute cloud of ultrac…
Measurement and numerical calculation of Rubidium Rydberg Stark spectra
Jens Grimmel, Markus Mack, Florian Karlewski +4
We report on the measurement of Stark shifted energy levels of Rb Rydberg atoms in static electric fields by means of electromagnetically induced transparency (EIT). Electri…
State-selective all-optical detection of Rydberg atoms
Florian Karlewski, Markus Mack, Jens Grimmel +2
We present an all-optical protocol for detecting population in a selected Rydberg state of alkali atoms. The detection scheme is based on the interaction of an ensemble of ultracol…
Quasiclassical theory of quantum defect and spectrum of highly excited rubidium atoms
Ali Sanayei, Nils Schopohl, Jens Grimmel +3
We report on a significant discrepancy between recently published highly accurate variational calculations and precise measurements of the spectrum of Rydberg states in Rb o…
Detrimental adsorbate fields in experiments with cold Rydberg gases near surfaces
H. Hattermann, M. Mack, F. Karlewski +3
We observe the shift of Rydberg levels of rubidium close to a copper surface when atomic clouds are repeatedly deposited on it. We measure transition frequencies of rubidium to S a…
Measurement of absolute transition frequencies of 87Rb to nS and nD Rydberg states by means of electromagnetically induced transparency
Markus Mack, Florian Karlewski, Helge Hattermann +4
We report the measurement of absolute excitation frequencies of 87Rb to nS and nD Rydberg states. The Rydberg transition frequencies are obtained by observing electromagnetically i…
