Using a camera with 2-picosecond time resolution, researchers show that the atoms in a laser-induced plasma are more highly ionized than theory predicts.<\/p>\n

With an astonishing 500 billion frames per second, a new movie captures the evolution of a laser-induced plasma, revealing that its atoms have lost more electrons\u2014and thus have stronger interactions within the plasma\u2014than models predict [1<\/a>]. The movie relies on a ten-year-old technology, called compressed ultrafast photography (CUP), that packs all the information for hundreds of movie frames into a single image. The results suggest that models of plasma formation may need revising, which could have implications for inertial-confinement-fusion experiments, such as those at the National Ignition Facility in California.<\/p>\n

Dense plasmas occur in many astrophysical settings and laboratory experiments. Their behavior is difficult to predict, as they often change on picosecond (10\u221212<\/sup> s) timescales. A traditional method for probing this behavior is to use a streak camera, which collects a movie on a single image by capturing a small slice of each movie frame. \u201cIt\u2019s one picture, but every line occurs at a different time,\u201d explains John Koulakis from UCLA. He and his colleagues have used streak cameras to study anomalous behavior in plasmas [2<\/a>], but the small region of plasma visible with this technique left doubts about what they were seeing, he says.<\/p>\n","protected":false},"excerpt":{"rendered":"
