The central result of our diffraction experiments is the observation of high-contrast interference for all gratings, where the contrast reaches its maximum when the interference minima approach the ...

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 ...

Enhancement of the Petawatt laser "LFEX" [1] up to 2,000 trillion watts for one trillionth of one second. High power output implemented by a 4-beam amplifier technology and the world's highest ...

This video illustrates a 180 nm, 30 µm, 11 Hz, scan of diffraction grating taken with Bruker’s Dimension FastScan atomic force microscope (AFM). The Dimension FastScan provides high resolution and ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

McPherson's SXR spectrometer, Model 251MX, is now available with improved efficiency over a wider range. A new diffraction grating is available! The new Gold coated diffraction grating is ideal for ...

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 ...

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, ...

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 ...
