Complex, three-dimensional (3-D) structures are regularly constructed using a reliable commercial method of 3-D laser micro- and nanoprinting. In a recent study, Frederik Mayer and co-workers in Germany and Australia have ...
When you heat a tiny droplet of liquid tin with a laser, plasma forms on the surface of the droplet and produces extreme ultraviolet (EUV) light, which has a higher frequency and greater energy than normal ultraviolet.
