Extending the laser pump X-ray probe system at LISA P08 PETRA III
Abstract The laser pump – X-ray probe setup at the LISA liquid interface scattering apparatus at beamline P08 at PETRA III enables investigation of photo-induced structural changes at liquid and solid interfaces with a time resolution of 38 ps. Here we report the latest upgrades on the pump – probe setup including the extension of the accessible pump-probe delay time scale and the implementation of laser beam profile transformers. The new laser optical cage system with magnetic holders allows variable laser beam sizes and flat top beam profile which can be advantageous for matching laser and X-ray beam size and profile on heat sensitive samples. The introduction of an additional delay/pulse generator now enables pump-probe measurements to be performed on all time scales from 100 picoseconds to seconds, allowing to study ultrafast and slow optical excitation and relaxation dynamics with any gap in time resolution.
