Infrastructure

For our experiments we use the Attoline setup which was originally conceived in the Ultrafast Laser Physics group and now is part of the FastLab platform. This setup is composed of a carrier-envelope-offset-stable Ti:sapphire amplifier system, pulse compression setups and a vacuum beamline that offers the generation of extreme ultraviolet (XUV) pulses down to attosecond duration. The amplifier offers pulse energies up to 10 mJ and its pulses can be compressed to few-cycle duration. It operates at 1 kHz pulse repetition rate. The XUV source covers photon energies in the range of 20 eV to 80 eV. The setup includes all equipment required for the generation and characterization of attosecond pulses. It supports time-resolved studies with attosecond temporal resolution and over time intervals of up to tens of picoseconds. It is equipped with detectors for photo-electron and XUV spectroscopy.
