Light is essential for life. For example, light is key to photosynthesis and vision. Light is also important in technology, such as in nanoscale optoelectronic devices. Developing a molecular-level understanding of light-induced processes is crucial for the rational design of new light-activated materials to address important challenges currently facing society, such as harnessing solar energy efficiently and developing new tools for disease diagnosis and therapeutics. Our vision is to establish a unique, state-of-the-art, laser facility providing femtosecond light pulses with a wide range of energies, from the infrared (IR) to the vacuum ultraviolet (VUV), housed in a £2M purpose-built, environmentally-controlled, stable basement laboratory. We will exploit this facility to improve our fundamental understanding of light-induced processes by using a bottom-up approach to study systems across the complexity scale, from isolated gas-phase molecules to proteins, nanoparticles, soft materials and solids, for applications ranging from bioimaging and therapeutics to solar energy materials. This will be achieved using a single spectroscopic technique, time-resolved photoelectron spectroscopy, in molecular and ion beams, liquid-microjets and surfaces, complemented by femtosecond transient absorption spectroscopy, femtosecond stimulated Raman spectroscopy and multi-photon microscopy.
