Spectroscopy of the 1001 nm transition in atomic dysprosium
Niels Petersen, Marcel Trümper, Patrick Windpassinger
We report on spectroscopy of cold dysprosium atoms on the transition and present measurements of the excited state lifetime which is at least $87.2(6.7)\,\mathr…

Sawtooth wave adiabatic passage slowing of dysprosium
Niels Petersen, Florian Mühlbauer, Lykourgos Bougas +3
We report on sawtooth wave adiabatic passage (SWAP) slowing of bosonic and fermionic dysprosium isotopes by using a 136 kHz wide transition at 626 nm. A beam of precooled atoms is…

Systematic optimization of laser cooling of dysprosium
Florian Mühlbauer, Niels Petersen, Carina Baumgärtner +2
We report on an apparatus for cooling and trapping of neutral dysprosium. We characterize and optimize the performance of our Zeeman slower and 2D molasses cooling of the atomic be…
