When individual atoms interact with each other, they often exhibit unusual behavior due to their quantum behavior. These effects can, for instance, be used to construct so-called quantum computers, ...
The USS Portland test-fires a laser weapon. The photo captured infrared light to make the beam visible. Staff Sgt. Donald Holbert/Marine Corps via AP Nations around the world are rapidly developing ...
When the green laser encounters atoms along its path through the crystal, it gives the electrons in those atoms a bit of extra energy. In their high-energy state, those electrons can absorb blue light ...
A beam of light can only be seen when it hits matter particles and is scattered or reflected by them. In a vacuum, however, it is invisible. Physicists at the University of Bonn, Germany, have now ...

Laser sculpting gives rare control over particle acceleration
Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a precision that once sounded like science fiction. Instead of simply blasting ...
A mysterious laser beam is shooting into the night sky in San Francisco this week. The beam is product of Barrett Lyon -- the CEO of Mega Laser and CTO of Tarsal, a data security company. Lyon is ...
Add Yahoo as a preferred source to see more of our stories on Google. (THE CONVERSATION) Nations around the world are rapidly developing high-energy laser weapons for military missions on land and sea ...
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 ...
Laser Devices Inc. (LDI) introduces the Dual Beam Aiming Laser-Advanced2 (DBAL-A2). DBAL-A2 is equipped with infrared and visible laser pointers (combined into a single laser module), and a focusable ...
