Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

Israel, the US, and other countries have worked on this technology. However, recent advances in technology have enabled ...

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 ...

Like robots, 3D-printing, space, and a handful of others, laser beams are undoubtedly classified under the “cool” side of science/technology. In the latest laser-beam related findings, Physicists from ...
