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 have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...
