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, ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead 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 ...

Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its ...

Metasurfaces and metalenses are advancing high-resolution imaging, providing exceptional light control and improving ...

As stated in the article titled ‘An Introduction to a Spectrometer: The Slit’, a spectrometer is an imaging system that maps a plurality of monochromatic images of the entrance slit onto the detector ...
