Description
The lowest-energy Thorium-229 isomeric state at 148.3 nm can be used to build a worlds-first nuclear clock. The transition is also sensitive to variations of the fine-structure constant and may be used to search for dark matter.
This poster presents the ongoing experimental progress towards building and optimizing a continuous-wave laser system at 148.38 nm and its use in high-precision fluoresence & absorption measurements of Thorium-229.
