We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Editor's Note: To view a PDF version of the article, Click Here. The commercial introduction of wafer-based, nanofabrication techniques now makes it possible to create a new class of optical ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS In a study published in Light: Science & Applications, researchers from Diamond Light Source (United Kingdom), ...
