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, ...

Inprentus won a TASA contract to produce diffraction gratings, closely following a recent NASA award, highlighting ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

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 ...

What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

FORT WAYNE, Ind. (WANE) – Martin Fisher visited First News Sunday for another edition of Science Sunday. Fisher brought a few items to demonstrate light diffraction. Using diffraction grating, a thin ...

Mimicking nature A material designed to mimic a quirky iridescent patch on a butterfly's wing may help prevent counterfeiting, say US engineers. The 'photonic' material, so called because it affects ...

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 ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...
