Our Team member from PTB, Dr. Johannes Tiedau has been selected as one of the five Werner von Siemens Fellows 2025. This prestigious fellowship recognizes
New Publication :: Noncollinear enhancement resonator with intrinsic pulse synchronization and alignment employing wedge mirrors
Abstract A noncollinear resonator with two beams circulating and intersecting in the focus allows resonator-assisted high-harmonic generation of high-power femtosecond pulses with efficient geometrical output
The first ultra precised nuclear clock is built!
We are extremely pleased to announce that together with JILA we have built the first ultra precise nuclear clock. After embedding a thorium-229 nucleus in
We did it !
We are overly excited to announce: Our teams from TU Wien and PTB Braunschweig successfully managed the laser excitation of the Th-229 Nucleus. The 8.4 eV
Storage and cooling of thorium ions from radioactive decay
Sympathetic cooling of Th3+ ions is demonstrated in an experiment where 229Th and 230Th are extracted from uranium recoil-ion sources and are confined in a linear Paul trap together with laser-cooled 88Sr+ ions.
New publications
Our teams have been busy developing the path towards a Nuclear clock. We are as excited to announce three publications that show some new and
