1D Magneto-Optical Forces in AlCl

Ultracold molecules promise access to a diverse range of high-impact research directions, including quantum simulation, ultracold chemistry, and precision measurement. Within this landscape, aluminum monochloride (AlCl) is a particularly strong candidate for quantum simulation applications. Its strong cycling transitions, favorable vibrational branching, and permanent electric dipole moment make it highly suitable for direct laser cooling and magneto-optical trapping. Here, we report the observation and characterization of 1D magneto-optical forces in an AlCl molecular beam. These measurements confirm the presence of forces necessary for magneto-optical trapping and lay the foundation for future cooling and trapping experiments. We present our recent results and discuss the path toward a 3D magneto-optical trap.
