Laser lights the way

Despite the enormous amount of research over the decades into lasers and their applications, there have been few ways to accurately, efficiently, and directly observe fine details of their interactions with materials. For the first time, researchers have found a way to acquire such data from a production laser using low-cost equipment that could vastly improve the accuracy of items cut or etched with lasers. Given the ubiquity of lasers, this could have wide-ranging implications in laboratory, commercial and industrial applications.
