Optically pumped research focuses on studying and developing methods for using light to pump energy into a system, typically an atomic or molecular gas, in order to excite its electrons and create a population inversion. This population inversion is then used to amplify light or create an intense beam of light, such as a laser beam. Optically pumped systems are commonly used in various applications, including spectroscopy, communications, and medical devices. The research in this area explores different techniques and materials for optically pumping systems, as well as optimizing their efficiency and performance.
