The coatings are designed to achieve the highest possible reflectivity at two specific laser line wavelengths at normal or 45 degrees incidence
	Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques

Dual Laser Line reflecting coatings provide an optimized performance at two certain wavelengths and certain angle of incidence (AOI). These multilayer coating stacks helps 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.
