Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a ...

And with the correct choice of laser wavelength, the light can destroy one type of material, while leaving others intact. Furthermore, laser power can be used in a blunt way, such as welding parts ...

The result is a darker area that appears as a shadow of the green laser beam. "This discovery expands our understanding of light-matter interactions and opens up new possibilities for utilizing ...

Shadows are a natural consequence of opaque walls in an illuminated Universe. Light shines; photons travel until they hit an object through which they cannot pass; this blockage creates a shadow ...

Researchers showed that a laser beam can sometimes act like a solid object and cast a shadow that is visible to the naked eye. In the picture, the shadow appears as the horizontal line traversing the ...
