Laser cooling and trapping of polar molecules has seen remarkable progress in the past decade, enabling applications in quantum information, quantum chemistry, and precision measurements. In particular, techniques such as laser cooling, magneto-optical trapping, sub-Doppler cooling, and long-lifetime trapping of polar molecules have been successfully demonstrated. This review highlights key achievements, including advancements in phase space density, with the long-term objective of achieving Bose–Einstein condensation in laser-cooled molecules. It also discusses the current challenges and potential strategies for reaching this milestone.
