The use of a Free-Electron Laser (FEL) allows the study of (non)linear optical properties of materials over unsurpassed large spectral intervals. As an example, we report on the use of a FEL as the infrared source in spectroscopic infrared-visible Su

We report on an experiment on spectroscopic infrared-visible Sum-Frequency Generation (SFG) with a Free-Electron Laser (FEL) as the IR-source. The SFG spectrum of gallium phosphide has been investigated in detail in an experiment covering the unsurpa

The influence of various rubbing parameters on the molecular reorientation of thin polyimide orienting layers, used to align liquid‐crystal (LC) molecules within liquid‐crystal displays, has been studied. For this purpose the optical phase retard

The anisotropic second-harmonic response has been calculated for vicinal (111) crystals misoriented from [111] towards or away from the [2 1 1 ] direction. Dipolar and quadrupolar surface and bulk contributions to the second-harmonic signal are consi
