This “diffraction grating” is a glass sheet covered with a thin film of gold. The many microscopic lines in the surface split light into various wavelengths when it is reflected. Gerard Mourou used this diffraction grate to first spread out a laser pulse, then amplify it, and finally transform it into a short laser pulse far more intense than the original. The damage to the surface is from experiments with laser light that was too powerful.
Gerard Mourou donated the diffraction grating to the Nobel Prize Museum in 2018.
