New laser shows what objects are made of | MconneX | MichEpedia

A new laser developed at Michigan Engineering can show what objects are made of. The system, which is made of off-the-shelf telecommunications technology, emits a broadband beam of infrared light. While most lasers emit light of one wavelength, or color, broadband lasers like this one give off a tight beam packed with columns of light covering a range of wavelengths -- a blend of colors. The beam the new laser emits is invisible, but it can illuminate deep information. By shining it on a target and analyzin
