Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...

The Iron Beam is the most advanced, operational laser in the world, though England, the US, and others have relatively advanced lasers. In a historic breakthrough, the IDF on Wednesday announced that ...

JERUSALEM – Israel has officially conscripted its new SIGMA 155 self-propelled howitzer and Iron Beam laser system, the ...

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 ...

Iron Beam, the world’s first laser air defense system, has officially entered service. The system was developed by Rafael ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...

Laser linewidth measures how precisely a beam of light maintains its frequency and color purity. The narrower the linewidth, the more monochromatic and spectrally pure the laser. The team's ...

How LBS technology enables a compact, power-efficient, and bright display engine. How MEMS-based LBS compares to panel-based display technologies. What’s the difference between the one-chip and ...
