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.

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, ...

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 ...

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 ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

Under the right conditions, a chaotic mess of laser light can spontaneously self-organize into a highly focused “pencil beam.” This schematic shows the pencil beam formation mechanism. CAMBRIDGE, MA - ...
