A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from ... and are even four orders of magnitude thinner than the width of a typical laser grating. As quantum ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

Up to now, optical combining elements such as gratings and dichroic mirrors for wavelengths around 2 µm were only available for laser powers of a few hundred watts. “However, our colleagues at the ...

Using specialized diffraction gratings, a laser, and a few lines of code, he explores a unique way of projecting hologram-like images on his path to the chocolate hologram. There’s a lot of ...

Here I am using the exact same diffraction grating with the same camera. The only difference is that I pointed the IR remote directly at the camera (for the laser pointers, I made a dot on a screen).

Every photon in a laser beam marches in lockstep ... including an off-the-shelf computer webcam and a small diffraction grating, a device for splitting and diffracting light into several beams ...

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 ...

A diffraction grating splits a beam of light up into multiple ... [Styropyro] uses a green laser as reference. This works for a couple of reasons; the green laser’s properties don’t change ...
