XUV / IR – Pulse Delay Unit


Our pulse delay unit makes use of our XUV/soft X-ray multilayer double mirrors and combines them with our profound knowledge in pump-probe experimental setups. The two-segment mirror facilitates focusing IR pulses and lower divergent XUV/soft X-ray pulses onto a common focus with an interferometrically precisely adjustable time delay. This allows temporal resolved experiments with pumping systems of interest either with the XUV/soft X-ray pulse and probe it with the IR or vice versa. Based on the nature of e.g. attosecond pulses generated in the XUV/soft X-ray range by High-Harmonic Generation (HHG) this offers state-of-the-art highest temporal resolution for your experiments. The mirror coating can be customized according to the center energy and bandwidth.
