Locking multiple lasers to a single optical cavity

One of the biggest unsolved problems in modern physics is the excess amount of matter compared to antimatter that exists in the universe. Charge parity (CP) symmetry violation could explain this imbalance, but there are not enough sources of CP violation to explain the size of the imbalance we observe. The nuclear magnetic quadrupole moment (nMQM) experiment at ODU seeks to perform precision measurements on Lutetium ions to look for sources of CP symmetry violation beyond what has been found in high-energy particle physics experiments. This experiment requires multiple lasers for laser-cooling and atomic state manipulation, which we must lock to a reference cavity. Locking multiple lasers to a single cavity can result in unwanted correlations between the lasers as thermal effects cause their feedback loops to interfere. For this project, we will lock multiple lasers to one cavity and characterize and then mitigate the amount of interference in this system.
