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 ...

The multi-axis grating interferometry for multi-axial displacement measurement is investigated. Two spatially separated laser beams are used to ensure that the ...

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 ...

In this paper, the implementation of coherent beam combining a seven-channel fiber laser is presented. Channel phase alignment is achieved using a two-stage stochastic parallel gradient algorithm. 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 ...
