Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

Physicists at the SLAC National Accelerator Laboratory just created a petawatt laser beam with the highest peak power and current ever. This beam was formed from a bunch of electrons that were ...

MIT researchers discovered a paradoxical phenomenon in optical physics that could enable a new bioimaging method that's faster and higher-resolution than existing technology. They discovered that, ...

Since the discovery of lasers, laser outputs have been limited to simple wavefront profiles, such as Gaussian (with the highest intensity in the middle, and lower intensity towards the tails) and ...

Scientists at MIT discovered that chaotic laser light can spontaneously form a highly focused beam instead of scattering—if the conditions are just right. This “pencil beam” enabled them to image the ...

Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow. The ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
