Optimized approach enables super-resolution 3D direct laser writing with unprecedented speed and resolution

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 direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and more. For the first time, researchers have used high-speed laser writing to create lines spaced just 100 nm apart on a glass substrate.
