Powered by laser light, this tiny sail lays the groundwork for future advances in lightsail technology and the potential for ...

However, Abrahao’s team demonstrated that under specific conditions, light itself—specifically, a laser beam—can block another beam, forming a visible shadow. “Our demonstration of a very ...

Cheap diode laser cutters and engravers operate in the visible part of the spectrum ... one used in the popular K40 machines, the infrared beam is invisible to the naked eye.

In 2024, seven vehicles in western China each transmitted a high-powered microwave beam that converged precisely in both time ...

To begin their research, the team built a small, tethered lightsail within a larger membrane. They then shined a visible ...

was started using laser beams from space. Greene, a freshman Republican from Georgia who made waves during the campaign for her promotion of the QAnon conspiracy theory, made the accusation in a ...

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships. It's a goal that sounds so fantastic, you'd be forgiven ...

Breakthrough Starshot is planning a laser beam, probably in the visible spectrum, that will push directly on light sails attached to the probe. However, given the current state of optical ...

A team of researchers at JILA, led by Professors Margaret Murnane and Henry Kapteyn, has developed a groundbreaking ...

Lasers are useful because they produce powerful beams of collimated ... to create light with a wide spectrum that can span the visible and near-infrared, typically from around 400 to 2,000 ...
