To achieve maximum efficiency in organic photovoltaics (OPV), functional layers with uniform and exactly predefined thickness are required. An in-depth understanding of the coating process is therefore crucial for an accurate process control. In this

Both the gas jet and the capillary setup have remarkable features for high-harmonic generation (HHG). We demonstrated both the ability of the capillary to tailor its spectral XUV output in unique ways, as well as the feasibility of the jet and its ab

We demonstrate the spatial homogenization of intense laser pulses by adaptive minimization of spatial chirp of the spectrally broadened output pulses of a filament. A liquid-crystal-based two-dimensional spatial light modulator is used to control the

Commercial picosecond sources have found widespread applications. Typical system parameters are pulse widths below 20 ps, repetition rates between 0.1 and 2 MHz, and microjoule level pulse energies. Most systems are based on short pulse mode-locked o

By adaptively controlling the mode structure in a gas-filled capillary with spatially shaped laser pulses we can manipulate the spatial and spectral properties of high-harmonic generation. This complements the control achieved by temporal pulse shapi

We have measured the wave front of high-order harmonics generated in a gas jet with a Hartmann sensor. With this setup we have investigated the influence of typical adjustable parameters such as gas pressure and focal position as well as the spatial
