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.

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 ...

Physicists at the SLAC National Accelerator Laboratory just created a petawatt laser beam with the highest peak power and current ever. This beam was formed from a bunch of electrons that were ...

The Iron Beam is the most advanced, operational laser in the world, though England, the US, and others have relatively advanced lasers. In a historic breakthrough, the IDF on Wednesday announced that ...

Laser linewidth measures how precisely a beam of light maintains its frequency and color purity. The narrower the linewidth, the more monochromatic and spectrally pure the laser. The team's ...

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 ...
