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

Scientists have beamed a laser into the sky, which was visible from miles around. The spectacle, known as The Beam, marked the 80th birthday of Harwell Science and Innovation Campus in Oxfordshire.

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 ...

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 ...

Russia is building a new ground-based laser facility for interfering with satellites orbiting overhead, according to a recent report in The Space Review. The basic idea would be to dazzle the optical ...

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