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 ...

Swiss physicists have achieved a groundbreaking breakthrough in lightning control using laser beams, which could lead to advanced lightning protection systems for critical infrastructure such as ...

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 ...

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 ...

Standard Operating Procedures (SOPs) are required for all Class 3B and Class 4 lasers and laser systems (including imbedded lasers if hazards are accessible), and must be approved by the Laser Safety ...
