In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

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 ...

These optical scanners comprise two separate, perpendicular planar mirrors that rotate independently. They are positioned in a manner wherein laser light bouncing off the first mirror (axis 1) ...

Israel will fully deploy the Iron Beam on December 30, introducing a laser system designed to intercept drones, rockets, missiles, and mortars at high speed. Defense Ministry research and analysis ...
