Extremely Fast Processes Recorded
KIEL, Germany, March 15, 2011 — Using pulses in the soft x-ray spectral region, scientists at the University of Kiel have demonstrated how quickly an intense laser can change the electrical properties of solids. The results of their research may lead to the development of optoelectronic components with faster data transmission rates or optical switches. This laser system generated the ultrashort x-ray pulses that were used in the experiment to make the recordings. (Images: Rohwer et al, University of Kiel) The new...
