Optical layout of the ZPM beamline after the upgrade in 2012. In order to select a certain lens and energy range, the optical element (RZPA, yellow) is traveled horizontally perpendicular to the optical axis driven by a stepping motor. A special laser feed-in (orange) is an inherent part of the approach enabling pump–probe experiments with variable pump wavelength from UV to MIR at large numerical aperture. |
