PARTIAL REFLECTION (PAR)

Partial Reflection coatings are widely used for beamsplitting, beam sampling and laser output coupling. They divide an incident beam into reflected and transmitted components with the specified intensity ratio. Coatings for high power wavelengths use special materials that are able to withstand higher power than standard partial reflection coatings. These all dielectric coatings are sensitive to polarization, wavelength and angle of incidence. They are durable and highly resistant to laser damage.

The Excimer laser coatings are able to withstand the corrosive properties of Excimer gases, thus are
well suited for intracavity applications.
