We report on the development and performance evaluation of an ultra-stable laser for 27Al+ optical clock. After a series noise suppressions, especially vibrational temperature fluctuation noise, 30 cm long cavity stabilized obtains frequency instability 1.3 × 10−16 @1 s. This result is predicted by summation confirmed three-cornered hat method. The clock transition also used to characterize consistent results are yielded. first reported instance using single ion clocks measure lasers, as far...
Accurate control of the polarization states laser light is important in precision measurement experiments. In experiments involving use a vacuum environment, stress-induced birefringence effect windows will affect inside system, and it very difficult to measure optimize situ. The purpose this protocol demonstrate how based on fluorescence ions calculate azimuthal angles external wave plates with Mueller matrix. 25Mg+ induced by that resonant transition |32P3/2,F = 4, mF 4 → |32S1/2,F 3, 3...
