Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a ...

Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on ...

Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to ...

In International Journal of Extreme Manufacturing, a new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

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 ...

Figure 1: Researchers at IFSW’s X-ray facility at the University of Stuttgart will study dynamic beam laser welding keyhole fluid dynamics with high-speed X-ray video imaging. Jerusalem, Stuttgart -- ...

When the green laser encounters atoms along its path through the crystal, it gives the electrons in those atoms a bit of extra energy. In their high-energy state, those electrons can absorb blue light ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...
