Wave-mixing phenomena (IMAGE)
Caption
Figure Caption: Two light beams from flashlights will not be influenced by each other when they cross. This is different for very intense laser pulses which meet in a suitable “nonlinear material” – here, beams can be deflected and new beams of different color can be created in a process called wave-mixing. The observation of such wave-mixing phenomena allows researchers to draw conclusions about electronic transitions within the nonlinear material which are otherwise invisible. Researchers from MBI and DESY have now observed how an x-ray beam interacts with a laser beam, paving a route to atom-selective studies of ultrafast processes in the future.
