Physicists have seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons to be ripped from their cores, accelerated, and then smashed back into the cores they left behind. This recollision produced multiple frequencies of light simultaneously.
