Illustration of 'electron lighthouse'

Caption

When two pulses of different colored lasers (the two waves at the top of the image) light meet in a new device created at the University of Michigan, researchers create a beam of electrons (small golden particles) that flows in a controllable direction. By changing the laser colors, the electron beam can sweep through different directions like the beam of a lighthouse.
