For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate. The optimized printing approach could enable super-resolution 3D ...

Researchers showed that their optimized direct laser writing approach could create high-resolution line gratings on a glass substrate. These SEM images show line gratings the researchers created using ...
