If Aliens Are Flashing Laser Beams at Us, We Now Have a Way to Detect Them. ... Tim Childers was a freelance science journalist with a background in physics and science communication.

Imagine shining two flashlight beams through each other — neither one blocks the other. However, some 3D computer models of laser systems depict the laser beam as a cylinder.

Researchers show how creating interference patterns with four laser beamlets improves the efficiency of energy transfer when accelerating electron and ion beams. This method can be used to enhance ...

Our approach uses laser beams to process multiple possibilities simultaneously, dramatically increasing computing power," says Dr. Isaac Nape, the Optica Emerging Leader Chair in Optics at Wits.

A triangle of three spacecraft shooting laser beams at each other in space sounds like something from a science fiction movie. However, the European Space Agency revealed this will become a ...
