Time and Frequency Department at the PTB in Braunschweig
Ekkehard Peik is head of the Time and Frequency Department at the PTB in Braunschweig, Germany, where he is working on atomic clocks and timescales. His research is focussed on optical clocks with laser-cooled trapped ions and on nuclear laser spectroscopy of the Th-229 low-energy isomer, motivated by the prospects for a nuclear clock and tests of fundamental physics.

Laser Excitation of the Th-229 Nucleus
The low-energy nuclear isomer state in Th-229 is resonantly excited in Th-doped calciumfluoride crystals using a tabletop tunable laser system at 148 nm wavelength. The experiment… (more)
