Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...
It's not at every university that laser pulses powerful enough to burn paper and skin are sent blazing down a hallway. But that's what happened in UMD's Energy Research Facility, an unremarkable looking building on the northeast ...
