The US and China are racing to build space-based solar power infrastructure that would beam electricity down to Earth 24/7.

Muons are unstable subatomic particles that spontaneously and rapidly transform into other particles via a process known as ...

Data from a recent integrated ground test of the Alpha high-energy laser, its beam director telescope and the associated beam alignment and correction system have provided the team developing the ...

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 ...

Since the discovery of lasers, laser outputs have been limited to simple wavefront profiles, such as Gaussian (with the highest intensity in the middle, and lower intensity towards the tails) and ...

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 ...

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.
