Description
Thorium-229 has a low-energy nuclear transition that has been excited
in thorium-doped crystals with laser light. This opens the perspective towards a highly stable and robust solid-state optical nuclear clock. We report recent progress in exciting the nucleus with a continuous-wave laser source and that the resonance signal can be detected in absorption rather than in fluorescence. This eliminates the slow nuclear fluorescence decay from the detection process and offers a considerable advantage for clock operation through fast signal acquisition.
