Coherent ultrabroadband XUV light source
Our High-Harmonic-Generation (HHG) setup consists of a vacuum chamber, all necessary KF vacuum components (incl. pump) and a fully motorized gas jet target. It generates XUV/Soft X-ray pulses through HHG when a (short) femtosecond laser is focused into the gas target. Moreover, single attosecond pulses can be isolated when NEPAL is combined with SAVANNA and our multilayer mirrors. A flexible access allows quick and easy exchange of the gas jet target. The breadboard inside the chamber is isolated from environment vibrations to improve the temporal and pointing stability of your experiment. A feedthrough for noble gas inlet is included to supply e.g. argon, neon or helium for HHG in the spectral photon range of interest. For example, few-cycle (4-5 fs) 800 nm pulses in neon can generate high harmonics up to 150 eV (8.3 nm). The final generated high-harmonic spectrum depends on the focused laser pulse parameters and the used noble gas based on phase-matching conditions.
