Continuous cloud position spectroscopy using a magneto-optical trap
Benedikt Heizenreder, Ananya Sitaram, Sana Boughdachi +4
We demonstrate a continuous spectroscopy technique with frequency sensitivity well below the natural transition linewidth, while maintaining a locking range hundreds of times large…

Quasi-continuous sub-K strontium source without a high-finesse cavity stabilized laser
Sana Boughdachi, Benedikt Heizenreder, Ananya Sitaram +8
We demonstrate a quasi-continuous sub-K strontium source achieved without the use of a high-finesse cavity-locked laser. Our frequency reference is based on a dispersion-optimi…

Spectral dynamics in broadband frequency combs with overlapping harmonics
Weichen Fan, Furkan Ayhan, Thibault Wildi +8
Optical frequency combs and their spectra of evenly spaced discrete laser lines are essential to modern time and frequency metrology. Recent advances in integrated photonic wavegui…
