During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Turin, Italy-based laser module manufacturer Convergent Photonics is developing new sources for high-power industrial and mid-power medical laser applications thanks to the introduction of a new ...

Accessibility of ultrafast lasers is increasing, with researchers, OEM tool builders and system integrators leveraging the power of these devices in a range of applications. Image Credit: PI (Physik ...

Metasurfaces offer an innovative approach to controlling light. Courtesy: P Genevet Vertical-cavity surface-emitting lasers (VCSELs) have emerged as a highly versatile light source over the past 30 ...

Mirror galvanometers (‘galvos’ for short) are the worky bits in a laser projector; they are capable of twisting a mirror extremely quickly and accurately. With two of them, a laser beam may be steered ...

Laser ablation is a process that uses high-energy laser pulses to precisely remove or vaporize materials from a solid surface. When the laser beam focuses on the target material, it absorbs the laser ...

(Nanowerk News) While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design complexity, the laser beams traditionally used in metal printing ...

Researchers at Northwestern University in Illinois have demonstrated the world's smallest remote-controlled walking robot. These tiny machines can bend, twist, crawl, walk, turn and jump without ...
