Towards the end of the 19th century, Abbe and Rayleigh formulated the principles of optical diffraction that limits the resolution of optical instruments in the far-field where the distance between ...

The team focused on an intense laser beam comprised of only low-energy photons, which incorporates two circularly-polarized carrier frequencies (a bi-chromatic beam). The polarization of the ...

Physicists have detected laser-assisted electron scattering using circularly polarized light for the first time, revealing new ways to probe atomic-scale chirality.

Now, adding a twisting laser beam that interacts with these electrons makes things even more complicated. And in that ...

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 ...

Scientists in South Korea have achieved a major milestone in physics – and one pursued by researchers in the field for decades – by generating a record-breaking ultra-high intensity laser. The pulse ...
