A low repetition rate optical frequency comb
Francesco Canella, Johannes Weitenberg, Muhammad Thariq +6
Reducing the pulse repetition rate of an optical frequency comb increases the pulse energy for a given average power. This enhances the efficiency of nonlinear frequency conversion…
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…
'Phase Transition' in the 'Thorium-Isomer Story'
P. G. Thirolf, B. Seiferle, L. v. d. Wense +3
Given the drastic progress achieved during recent years in our knowledge on the decay and nuclear properties of the thorium isomer 229mTh, the focus of research on this potential n…
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…
Nuclear clocks for testing fundamental physics
E. Peik, T. Schumm, M. S. Safronova +3
The low-energy, long-lived isomer in Th, first studied in the 1970s as an exotic feature in nuclear physics, continues to inspire a multidisciplinary community of physicist…
The theory of direct laser excitation of nuclear transitions
Lars von der Wense, Pavlo V. Bilous, Benedict Seiferle +5
A comprehensive theoretical study of direct laser excitation of a nuclear state based on the density matrix formalism is presented. The nuclear clock isomer Th is d…
