"Less than a year after it was first suggested, the world’s first antilaser is here. A team of physicists have built a contraption that, instead of flashing bright beams, utterly extinguishes specific wavelengths of light. Conventional lasers create intense beams of light by stimulating atoms to spit out a coherent beam of light in which all the light waves march in lockstep. The crests of one wave match the crests of all the others, and troughs match up with troughs. The antilaser does the reverse: Two perfect beams of laser light go in, and are completely absorbed."
