Is it possible to 3d print a diffraction pattern? Martin Lewis issues warning over using debit cards Russell Crowe details health woes as he reveals the secret behind his 26kg transformation Mona has ...

Abstract: We fabricated 1-D diffraction grating on the end surface of cleaved hollow optical fibers with a direct inscribing method using femtosecond laser pulses, and measured the beam shape patterns ...

A diffractive optic creates two DUV beams, which are focused and interfered on a sample surface (diamond) using a 4f imaging system to generate a microscopic sinusoidal excitation profile. Credit: ...

This Stevens doctoral student uses complex quantum theories and equations to help build real nanostructures that could aid navigation, sensing and more Growing up on the east side of Nigeria’s capital ...

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 ...

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 ...
