Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In ...

North Carolina State University researchers have used a laser to create the first demonstrated plasma beam antenna, a tunable ...

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

Scientists have demonstrated a remarkable new antenna that resembles a lightsaber, using a laser to create a tunable beam of plasma capable of transmitting radio waves. The technology could ...
