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.

Obviously the wavelength of a laser can’t be measured with a scale ... [Styropyro] uses a CD as a diffraction grating which results in an optical pattern large enough to measure.

Reflective ruled diffraction ... SBC grating). High-quality ruled diffraction gratings can meet almost all diffraction needs, especially when the efficiency requirements are relatively high.

We call this monochromatic. The light produced ... Here you can see the laser, the diffraction grating (with reflections) and the dots on the screen. This is exactly what the Christmas laser ...

The laser beam has to be expanded by intracavity optics, in order to fill the grating aperture and obtain high resolution. The Littrow configuration is also often used for external cavity tuning of ...
