Home > Coatings Section > DAR - Dual Anti-Reflection Coatings
Frequently used in multi-frequency laser output systems (e.g. frequency doubling)
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques

Dual AR coatings designed to reduce the reflectivity of a component to near-zero for two certain wavelengths. Usually these coatings are used in multi-frequency laser output systems (e.g. frequency doubling). This coating provides very high transmission at two different wavelengths. Typical wavelengths and reflection curves of an AR coating suitable for the prevalent laser system output at 1064 nm and 532 nm are shown below.
