Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of grooves ...

Laser tuning gratings are holographic gratings specially designed for wavelength tuning of lasers, such as dye lasers, Ti-sapphire, or external cavity diode lasers. The groove depth is optimised to ...

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 ...

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, ...

Spectrographs are important tools for studying many biological and chemical processes and substances, from pigments to plant growth and nucleic acids to pharmaceuticals, providing information about ...

Soft X‐ray diffraction gratings coupled with advanced multilayer coatings represent a pivotal innovation in the development of high‐resolution spectroscopic instruments. These devices utilise periodic ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...

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 ...
