To achieve this, a pulsed laser will be focused on samples together with the Xray beam used to perform absorption spectroscopy. The laser setup is placed in a dedicated clean room from which an 85mm diameter beam is transported in the experimental hutch to the laser/sample interaction chamber thanks to a 15m long optical system. The laser beam is then focused down to 250 micrometres on the sample. Operating ID24-ED at different energies requires the samples to be rotated by about 40 degrees around the last Xray optical element of the beamline, a polychromator placed 1m upstream of the sample. The movement of the sample and the need for the laser to follow it put strong constraints on the mechanical design of the whole setup. We will present the layout of laser facility, the opto-mechanical system of mirrors and lenses used to transport the laser onto the sample, the kinematics of the mechanical system used to follow the rotation of the sample and the mechanical design of the interaction chamber.
