Project PRISM aims to develop a highly efficient laser system that can be pumped with polychromatic light and has a monochromatic output. Since the properties of such a media are defined by its molecular construction, we need to determine the exact molecular structure and composition based on our target characteristics. In order to do so, we developed a learning algorithm combined with quantum chemical simulation. At the end of our project, we want to present a molecule (for doping the medium) that allows us to design a monochromatic laser system capable of using a polychromatic pump source.
