When certain atoms are irradiated with laser light, they can produce a very different kind of laser light: laser pulses with extremely high frequencies in the X-ray range.

With its marching bands, billowing flags and precision drills, the Tattoo has never exactly been cutting edge. But now an experimental theatre-maker has been let loose on it … Dusk has settled on Edinburgh Castle and now a laser beam is scribbling a route across its ramparts and

Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that quantum entanglement between photons can be generated directly from sunlight, offering a pote

Supercontinuum light sources—often called "white lasers" because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. However, researchers have historically faced a frustrating trade-off:

Facing a growing drone threat, the Pentagon is poised to sign a first-of-its-kind contract for “Enduring High Energy Lasers”—and make directed energy weapons an official part of the Army’s kit.

Hairmax’s LaserBand 82 ComfortFlex took only 90 seconds per treatment, and it produced visible results along my widening part.

Using a combination of laser cooling techniques and strong magnetic fields, researchers at Colorado State University have for the first time created an ultracold neutral plasma with electrons cooled to temperatures measured to be within one degree Kelvin.

For the first time, researchers have determined the shape of the actinide nucleus of fermium-255 and measured its structure with high precision and resolution.

A descoberta, feita com uma tecnologia que usa lasers, desafia a visão de que a região era pouco habitada em tempos pré-colombianos.

Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called polaritons. This makes the platform not only a new ty

Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology. Their outdoor experiment produced entangled photons with about 94% similarity to an ideal state. The result co

Novo pulso óptico consegue duplicar a energia de elétrons acelerados, superando limitação que há décadas restringia esses equipamentos. Descoberta promete transformar a pesquisa em física de alta energia.
