When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ...

Add Yahoo as a preferred source to see more of our stories on Google. A major scientific breakthrough could change how we understand and control ionization — the process where atoms lose electrons 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 ...

For more than half a century, the search for extraterrestrial intelligence has been built on the assumption that if aliens exist and try to communicate, their signals will be faint, scattered, 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 - ...
