Conventional particle accelerators can range from large room-sized devices to facilities multiple kilometers across. One of the ways that scientists have looked to reduce the size and expense of future accelerators is by developing laser -driven plasma acceleration. Such accelerators, however, are growing in size and complexity in order to maintain relevance for one of their applications-high energy physics. However, there are many applications that can use a lower energy and higher repetition rate accelerated beam. For the first time, scientists have observed the production of relativistic electrons driven by low-energy, ultrashort mid-infrared laser pulses. A research team at the University of Maryland, USA, with support from the Technical University of Vienna, Austria, will present their group`s findings at Frontiers in Optics + Laser Science APS/DLS (FIO + LS), held 17-21 September 2017 in Washington, DC.
