Home > Coatings Section > PR - Partial Reflecting Coatings
Efficient beam splitting as well as output coupling in high power laser cavities
Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques

Partial reflecting coatings provide required percentage reflection/ transmission at a specific angle of incidence both for both single and broad band wavelenghts. These coatings serves usually for the efficient beam splitting as well as output coupling in high power laser cavities.
