Wide-bandwidth atomic magnetometry via instantaneous-phase retrieval
Nathanial Wilson, Christopher Perrella, Russell Anderson +2
We develop and demonstrate a new protocol that allows sensing of magnetic fields in an extra-ordinary regime for atomic magnetometry. Until now, the demonstrated bandwidth for atom…
Observation of Dynamic Stark Resonances in Strong-Field Excitation
Dashavir Chetty, Rohan D. Glover, Bruno A. deHarak +12
We investigate AC Stark-shifted resonances in argon with ultrashort near-infrared pulses. Using 30 fs pulses we observe periodic enhancements of the excitation yield in the intensi…
Light-shift spectroscopy of optically trapped atomic ensembles
Ashby P. Hilton, Andre N. Luiten, Philip S. Light
We develop a method for extracting the physical parameters of interest for a dipole trapped cold atomic ensemble. This technique uses the spatially dependent ac-Stark shift of the…
Heterodyne fiber interferometer for frequency-noise reduction and rapid wide-band tunability of a conventional laser source
Ashby P. Hilton, Philip S. Light, Lauris J. B. Talbot +1
Self-heterodyne fiber interferometers have been shown to be capable of stabilizing lasers to ultra-narrow linewidths and present an excellent alternative to high finesse cavities f…
Dual-colour magic-wavelength trap for suppression of light shifts in atoms
Ashby P. Hilton, Christopher Perrella, Andre N. Luiten +1
We present an optical approach to compensating for spatially varying ac-Stark shifts that appear on atomic ensembles subject to strong optical control or trapping fields. The intro…
