Figure 3. A photo of the high-harmonic generation (HHG) process. In this photo, we look into the HHG vacuum vessel from a window on the top. The drive IR pulse laser (propagating from left to right) is focused on a pressurized Argon gas jet between a gas nozzle and a gas catcher (placed along the vertical direction).  The bright white plasma generates higher harmonics in the 10-20 nm wavelength range. The colourful glow and streak, shown as purple-pink by the camera, originate from the scattered IR light (courtesy Sven Weerdenburg).
