K2
XUV / IR – Pulse Delay Unit
Our pulse delay unit K2 is a handy tool to design your pump-probe experimental setup. It uses our XUV/soft X-ray multilayer double mirrors and the coating can be customized for the specific center energy and bandwidth needed.
The two-segment mirror focuses IR pulses and lower divergent XUV/soft X-ray pulses onto a common focus with a precisely adjustable time delay. This enables time resolved experiments either with the XUV/soft X-ray pulse pumping the system and the IR pulse probing it, or vice versa. With attosecond pulses generated in the XUV/soft X-ray range by High-Harmonic Generation (HHG), K2 offers the highest temporal resolution for your experiments.
