Experimental set-up (alternative) (IMAGE) University of Göttingen Caption An infrared laser pulse (shown as a dark red oscillating wave) has been tightly focused into pure water where a plasma (green cloud) is formed; a shock wave and a bubble (hemispheres) are then created. An acoustic signal recorded with a microphone is used to determine the deposited energy, a diverging X-ray beam (purple cone) is used to image a hologram captured by a detector.
