Workpackage 3 : improvement of the HHG seed
Schematic drawing of the experimental setup for seeding HHG into a soft x-ray laser amplifier. The spectra (HHG, amplified HHG) displayed have been achieved experimentally.
Interference fringes obtained using the Young’s slit setup with a HHG beam emitting around 32 nm.
Horizontal plot of the image of the interference fringes, showing a very high contrast. The HHG beam is highly coherent.
