Description
The NL-eEDM collaboration aims to probe the CP-violating electron electric dipole moment (eEDM) using BaF molecules [1]. The measurement requires frequency-dependent hyperfine state detection. In the current scheme [2], the fluorescent light is not distinguishable from the probe light, resulting in the scattered light from the probe laser dominating the background. We introduce a new laser induced fluorescence detection scheme, in which molecules are excited to the DΣ state with blue light, and a pair of infrared photons is detected. We will present spectroscopy results of this transition, and evaluate its influence on the sensitivity to the eEDM using BaF.
