XUV/IR pulse delay unit K2
Attosecond time-resolved pump-probe experimentsGarching (München), )
Its design allows to focus two collinear laser beams of different divergence/beam size establishing highly stable spatial overlap between their foci while providing precisely adjustable time delay. The 5 degrees of freedom adjustment ensures a perfect spatial and temporal overlap. In addition, the energy and bandwidth of the mirror can be customized to the user needs.
The high precision provided by K2 is perfect for XUV-IR pump-probe experiments such as attosecond streaking, RABBITT (reconstruction of attosecond beating by two-photon transitions), attosecond transient absorption and other time-resolved IR-XUV measurement techniques.
