(Phys.org)—It was a very good week for physics as a team of researchers from China and Israel made the first observation of the pushing pressure of light—they were able to show the surface of a liquid bending inward when ...
A group of Russian scientists recently presented their research into the process of laser pulse filamentation—the effect produced when a laser beam propagating in air focuses into a filament. The researchers discovered ...
