Optics Introduction to Diffraction Grating
Introduction to Diffraction Grating www.thorlabs.com Diffraction Gratings (Ruled and Holographic) Diffraction gratings can be divided into two basic categories: holographic and ruled. A ruled grating is produced by physically forming grooves on a reflective surface by using a diamond tool mounted on a ruling engine. The distance between adjacent

The modeled laser pulses (top) and CW laser output (bottom) provide the same energy per period, illustrated by the shaded areas. The CW laser's output power equals the pulsed laser's average power.

ELECTRON DIFFRACTION
faraday.physics.utoronto.caINTRODUCTION This experiment is a demonstration of the wave nature of the electron, and provides a confirmation of the de Broglie relationship: (1) h p where = electron wavelength, h = Planck's constant, p = electron momentum. It also provides an introduction to the use of diffraction in the analysis of crystals.
