Number-Resolved Detection of Dark Ions in Coulomb Crystals
Fabian Schmid, Johannes Weitenberg, Jorge Moreno +3
While it is straightforward to count laser-cooled trapped ions by fluorescence imaging, detecting the number of dark ions embedded and sympathetically cooled in a mixed ion crystal…
Motional resonances of three-dimensional dual-species Coulomb crystals
Byoung-moo Ann, Fabian Schmid, Jonas Krause +3
We investigate the motional resonances of dual-species Coulomb crystals comprised of Be and Mg ions held in a 4-rod linear Paul trap. Our experimental data and s…
Simple phase noise measurement scheme for cavity-stabilized laser systems
Fabian Schmid, Johannes Weitenberg, Theodor W. Hänsch +2
We describe a simple method for measuring the residual fast phase noise of a cavity-stabilized laser using the cavity as a reference. The method is based on generating a beat note…
High repetition pump-and-probe photoemission spectroscopy based on a compact fiber laser system
Y. Ishida, T. Otsu, A. Ozawa +4
The paper describes a time-resolved photoemission (TRPES) apparatus equipped with a Yb-doped fiber laser system delivering 1.2-eV pump and 5.9-eV probe pulses at the repetition rat…
Cavity-enhanced dual-comb spectroscopy
Birgitta Bernhardt, Akira Ozawa, Patrick Jacquet +7
The sensitivity of molecular fingerprinting is dramatically improved when placing the absorbing sample in a high-finesse optical cavity, thanks to the large increase of the effecti…
