Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

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 ...

Laser beam interactions with plasma are at the forefront of contemporary high-energy density physics, offering transformative potential in areas ranging from inertial confinement fusion to advanced ...

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 ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

On the night of October 17, 2015, as a passenger aircraft descended to an altitude of 300 meters on its way to land at Osaka International (Itami) Airport, a green light, believed to be a laser, was ...
