A low-cost confocal microscope for the undergraduate lab
A. Reguilon, W. Bethard, E. Brekke
We demonstrate a simple and cost-efficient scanning confocal microscope setup for use in advanced instructional physics laboratories. The setup is constructed from readily availabl…
3D Printing an External Cavity Diode Laser Housing
E. Brekke, T. Bennett, H. Rook +1
The ability to control the frequency of an external-cavity diode laser (ECDL) is an essential component for undergraduate laboratories and atomic physics research. Typically the ho…
Saturation and alternate pathways in four-wave mixing in rubidium
E. Brekke, N. Swan
We have examined the frequency spectrum of the blue light generated via four-wave mixing in a rubidium vapor cell inside a ring cavity. At high atomic density and input laser power…
Excitation Suppression Due to Interactions Between Microwave-Dressed Rydberg Atoms
E. Brekke, J. O. Day, T. G. Walker
Atom-atom interactions within a small volume were investigated through the excitation of ultracold Rb atoms. The application of microwaves enhances these interactions, causing the…
Four-Wave Mixing in Ultracold Atoms using Intermediate Rydberg States
E. Brekke, J. O. Day, T. G. Walker
Ultracold Rb atoms were used to demonstrate non-degenerate four-wave mixing through a Rydberg state. Continuous 5S-5P-nD two-photon excitation to the Rydberg state was combined wit…
Dynamics of Low-Density Ultracold Rydberg Gases
J. O. Day, E. Brekke, T. G. Walker
Population dynamics in weakly-excited clouds of ultracold Rb Rydberg atoms were studied by means of trap loss, fluorescence detection, and state dependent stimulated emissio…
