Scientists have reimagined the meaning of a "light meal," creating microlasers that use natural products to emit illuminated beams through food. And they're completely edible. These mini lights, the ...

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign ...

How can tunable lasers contribute to society? This is what a recent study published in Optica hopes to address as an ...

Laser tattoo removal Laser devices remove tattoos using very specific wavelengths of light that target the pigment in ink. Different colours require different wavelengths. The precise beam of the ...

Researchers have discovered a powerful new way to shield atoms from losing quantum information, a long-standing hurdle in building reliable quantum technologies. By using a single, carefully tuned ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing ...

A team at Harvard and Vienna University of Technology have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...

The characteristics of laser beam by the compensation of thermal lensing effect in a fiber- coupled laser-diode ceramic Nd:YAG laser was investigated. Using a compensator, the divergence and M of the ...

UF engineers, backed by DARPA and NASA, are perfecting laser-forming techniques that let metal sheets fold themselves into giant solar arrays, antennas, and even space-station parts right in ...

We compare narrow and wide laser beams in a free-space optical (FSO) communications system for high-speed train communications and analyze the tradeoffs among the received power, coverage area, and ...

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS) imaging of surfaces and tissues is a rapidly evolving technique having great potential in the field of ...
