After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, scientists decided to experiment in real life — and found that laser beams ...

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 ...

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 ...

NTT Inc. and Mitsubishi Heavy Industries Ltd. (MHI) conducted an optical wireless power transmission experiment using a laser beam to wirelessly transmit energy over a distance of one kilometer. By ...
