Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a ...

(THE CONVERSATION) Nations around the world are rapidly developing high-energy laser weapons for military missions on land and sea, and in the air and space. Visions of swarms of small, inexpensive ...

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 ...

There are many different types of lasers—almost as many as there are applications for the same—but what ties them all together as a class is that they depend on the same physical effect: stimulated ...

Earlier this summer, Israel made military history. Not with a missile, bomb or bullet — but with a beam of light. In a first for modern warfare, the Israel Defense Forces successfully intercepted ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...
