In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Physicists at the University of Warsaw have generated a miniature “laser tornado” inside nanoscale structures by engineering a synthetic magnetic field for photons. The work, announced in March 2026, ...

Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with ...

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 ...

Some scientific achievements are large and flashy—like imposing robots—while others are incredibly small, fast, and nearly invisible. And as a record-breaking laser pulse reported by scientists in a ...

Researchers at North Carolina State University have demonstrated a laser-powered plasma antenna that transmits radio signals ...

Building off a breakthrough "anti-laser," a team of researchers has developed a system that can direct light and other electromagnetic waves for signal processing without any unwanted signal ...

A laser pointer's beam can reach miles into the sky, yet its bright dot seems to vanish on your TV. Here's what's actually happening to that light.

Researchers are blurring the lines between science and art by showing how a laser can be used to create artistic masterpieces in a way that mirrors classical paints and brushes. The new technique not ...
