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 ...

(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 ...

Spreading the laser beam's intensity out reduces the temperature difference between sections of the part being printed. Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make ...

In the past various methods have been employed for heat treating metals, which is usually carried out using large furnaces where an entire object undergoes the heating process. These processes have ...

While beam-shaping strategies have allowed researchers to sculpt the cross-sectional shape of laser spots—using, for example, triangular beams to carve triangular channels—the interaction of such ...
