Guidelines for designs for ultrastable laser with fractional frequency instability
Joannès Barbarat, Erik Benkler, Marcin Bober +46
Lasers with long coherence time and narrow linewidth are an essential tool for quantum sensors and clocks. Ultrastable cavities and laser systems are now commercially available wit…

Using slow light to enable laser frequency stabilization to a short, high-Q cavity
David Gustavsson, Marcus Lindén, Kevin Shortiss +4
State-of-the-art laser frequency stabilization is limited by miniscule length changes caused by thermal noise. In this work, a cavity-length-insensitive frequency stabilization sch…

Pushing the limits of negative group velocity
Antonius J. Renders, David Gustavsson, Marcus Lindén +4
Distortion free negative group velocity pulse propagation is demonstrated in a rare-earth-ion-doped-crystal (RE) through the creation of a carefully designed spectral absorption st…
