Edge of titanium crater formed by a laser. Coloured scanning electron micrograph (SEM) of the edge of a nanoscale crater formed on a titanium surface by a laser beam. Titanium is a metal element. This crater was produced during research that involves the use of lasers to etch and ablate metal and semiconductor surfaces. The resulting nanostructures can have applications in various forms of electronics and nanotechnology.
