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, ...

Researchers developed a process to turn crab shells into a bioplastic that can be used to make optical components known as diffraction gratings (in the tweezers).

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Calculated diffraction pattern on a two-dimensional Raman induced grating as a function of the diffraction angle and pump field intensity. Disclaimer: AAAS and EurekAlert! are not responsible for the ...

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 ...

A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...
