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 ...

(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 ...

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

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 ...

RGB multiplexer based on thin-film lithium niobate enables faster and more efficient light modulation for laser beam scanning systems As technology advances, photonic systems are gaining ground over ...
