Abstract
Section titled āAbstractāPump-probe spectroscopy is a well-established technique used to monitor the dynamics occurring in any state of matter, in timescales ranging from attoseconds to seconds and beyond. When performed at synchrotrons the technique offers probe with high repetition rate, wide scanning capabilities in terms of energy, spatial resolution at the nanometre scale, and elemental specificity. Recently, recognizing the impact and importance of such experiments across its science spectrum, Diamond with the strong support from the UK academic community, invested and deployed a novel laser source, PORTO, which can be used in various beamlines for pump-probe experiments. PORTO is a portable femtosecond laser system which has been used so far, for optical-pump and X-ray-probe absorption (XAS) and diffraction (XRD) experiments. Here we present its main characteristics and capabilities as well as its application in the areas of plasmonic photocatalysis and coordination chemistry, along with recent results about the ultrafast dynamics of hot electron ejection from plasmonic nanoparticles to semiconductor materials used in the field of plasmonic N2 photofixation.
