China’s Harbin Xinguang Optic-Electronics Technology debuted two man-portable laser weapons at the Defence Information ...

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 ...

How do you measure the inside of a cave? You could do a bunch of hard work with classic surveying gear… or you could just use a laser scanner. [9nl] did the latter, with a scanning rig of ...

Laser material processing uses high-intensity light beams in material fabrication. This can include cutting, engraving, drilling or welding metals. It can also include cleaning materials with lasers.
