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 ...

Stabilized multi-wavelength emission from a single emitter broad area diode laser (BAL) is realized by utilizing an external cavity with a spectral beam combining architecture. Self-organized emitters ...

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 ...

We propose and demonstrate a continuous-wave all-fiber ring laser generating cylindrical vector beams (CVBs) using a mode selective coupler (MSC) as transverse mode converter and mode splitter. 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 ...
