Much to the distaste of James Bond villains everywhere, scientists from Yale University recently demonstrated not a new, more powerful type of laser, but actually its opposite – the world’s first anti-laser. The device receives incoming beams of light, which interfere with one another in such a way as to cancel each other out. It could apparently have valuable applications in a number of technologies, such as optical computing and radiology.
