Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

However, aluminum is tricky. The element is difficult to measure with lasers, as well as cool to absolute zero. But when ...

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 ...

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 ...

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 ...

NASA tested laser communications from space with a video of a cat chasing a laser dot! Psyche beamed the video about 19 million miles back to Earth.

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 ...
