Two-photon polymerization (TPP) and direct laser writing (DLW) techniques utilise focused ultrashort laser pulses to induce highly localised photochemical reactions in photosensitive materials, ...

Researchers developed a new optimized printing approach that could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and ...

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 ...

Femtosecond laser writing is a transformative technique that utilises ultrashort laser pulses to locally modify the refractive index of a material, enabling the fabrication of intricate ...
