The Anti-Laser's Light-Swallowing Act

Lasers amplify light. The name itself is an acronym for "Light Amplification by Stimulated Emission of Radiation." It's only natural then that the world's first anti-laser cancels light, and could spark applications in optical supercomputing and radiation oncology. "Our device is a laser that works backwards, absorbing light at specific frequencies rather than emitting it," said Yale University physics professor Hui Cao.
