Partial Reflection (PAR)
193
nm ≤ λ ≤ 400 nm
Partial Reflection coatings are widely used for beamsplitting, beam
sampling and laser output coupling. They divide an incident, monochromatic
beam into reflected and transmitted components with the specified intensity
ratio. The Excimer laser coatings are able to withstand the corrosive
properties of Excimer gases, thus are well suited for intracavity applications.
These all dielectric coatings are sensitive to polarization, wavelength
and angle of incidence. They are durable and highly resistant to laser
damage.
