Using strain to control echoes in ultrafast optics
Experimental setup for tele-ptychography at NanoMAX beamline. Credit: Angel Rodriguez-Fernandez Researchers at MAX IV measured echoes produced by silicon crystals using the coherent X-ray based technique, tele-ptychography, at NanoMAX imaging beamline. Their findings reveal that strain can be used to tune the time delay of echoes, an important step for tailoring ultrafast X-ray optics. “The
