The coatings are designed to achieve the highest possible reflectivity at two specific laser line wavelengths at normal or 45 degrees incidence
Description
Dual Laser Line mirrors (DHR) provide an optimised performance at two certain wavelengths and certain angle of incidence (AOI).
These multilayer coatings are stacks intended to achieve the highest possible reflectivity at two specific laser line wavelengths at normal or 45 degrees incidence. Laser line high reflectivity coatings are intended for external beam manipulation applications where even slight losses may be intolerable.
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques.
