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, who invented the device with fellow Yale physics professor A. Douglas Stone and published the results in the Feb. 18 issue of the journal
