A laser system for the excitation of rubidium Rydberg states using second harmonic generation in a PPLN waveguide crystal
Andreas Koglbauer, Peter Würtz, Tatjana Gericke +1
We report on a laser system at a wavelength of 495 nm which is suitable for the excitations of low lying Rydberg states of rubidium atoms. The system is based on frequency doubling…
Ultracold Atoms as a Target: Absolute Scattering Cross-Section Measurements
P. Würtz, T. Gericke, A. Vogler +1
We report on a new experimental platform for the measurement of absolute scattering cross-sections. The target atoms are trapped in an optical dipole trap and are exposed to an inc…
AC-Stark shift and photoionization of Rydberg atoms in an optical dipole trap
F. Markert, P. Würtz, A. Koglbauer +3
We have measured the AC-Stark shift of the Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO-laser. We find good quantitative agreement…
Experimental demonstration of single-site addressability in a two-dimensional optical lattice
Peter Würtz, Tim Langen, Tatjana Gericke +2
We demonstrate single site addressability in a two-dimensional optical lattice with 600 nm lattice spacing. After loading a Bose-Einstein condensate in the lattice potential we use…
High Resolution Imaging of Single Atoms in a Quantum Gas
Tatjana Gericke, Peter Würtz, Daniel Reitz +2
Our knowledge on ultracold quantum gases is strongly influenced by our ability to probe these objects. In situ imaging combined with single atom sensitivity is an especially appeal…
All-optical formation of a Bose-Einstein condensate for applications in scanning electron microscopy
T. Gericke, P. Wuertz, D. Reitz +2
We report on the production of a F=1 spinor condensate of 87Rb atoms in a single beam optical dipole trap formed by a focused CO2 laser. The condensate is produced 13mm below the t…
