Mixing laser- and X-ray-beams

Unlike fictional laser swords, real laser beams do not interact with each other when they cross – unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing can give rise to beams with changed colors and directions.

Wave-mixing processes between different light beams are one cornerstone of the field of nonlinear optics, which is ...

Using X-rays to identify liquid mirror molecules

Sugars, amino acids, drugs - chiral molecules that come in two mirror forms are everywhere. Researchers in the AQUACHIRAL project at the Fritz-Haber-Institut (FHI) have used PETRA III to study hair-thin liquid jets of these molecules. Using a new method, they can now for the first time distinguish their components in liquid form – and more effectively than ever before, as the ...

Reconstructing the refraction and attenuation in a sample directly from scattered X-rays

In X-ray microscopy, it is often the optics that limit spatial resolution or cause distortion in the image. A radical way to get around this problem is to omit the optics altogether. The price of this ‘lensless’ microscopy is that the image must be calculated from the intensity pattern formed on the detector by the light scattered from the sample. But the calculation yields more than just an image: It provides a ...
