Laser-Line RMAX High Reflection coatings provide maximum reflectivity
with very low loss due to absorption and scatter. The Excimer 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.

Polarizing Cube Beamsplitter coatings are deposited between two optically
contacted, right angle prisms. They are designed to separate an incident,
unpolarized, monochromatic beam into its S and P polarization components
with an extinction ratio (Tp/Ts) in excess of 200:1.
The incident energy is split into two orthogonal beams that emerge at
90º with respect to each other. These coatings are also useful
for combining two orthogonally polarized beams.

Phase Retarding Mirror coatings are designed to produce a specific phase shift between the S and P polarization components of an incident CO2 laser beam. Coatings designed for 0º phase
shift maintain the incident polarization state in the reflected beam. Coatings designed for λ/4 (90º)
phase shift convert a linearly polarized beam into a circularly polarized beam. Coatings designed for λ/8 (45º)

Bare Aluminum offers greater than 86% reflectance from near UV to mid IR. Aluminum will slowly oxidize, resulting in a significant loss of reflectance in the UV, and slight scattering throughout the spectrum. Therefore, it is best if aluminum has a protective dielectric overcoat. A protective overcoat will also substantially improve abrasion resistance, so that the coating is less susceptible to damage during cleaning and handling.

Bare Gold has high reflectance in the near, mid and far IR regions. Gold does not oxidize, so it is not necessary that it have a protective dielectric overcoat. However, bare gold is very soft and easily scratched, and can only be cleaned by flow-washing with solvents, or by blowing the surface clean with a low pressure stream of dry air. Durability is greatly enhanced with a protective overcoat. Protected gold can be cleaned regularly using standard organic solvents. Gold is chemically inert, thus it is well suited for harsh environments, such as DF and HF laser cavities.

is overcoated with a black epoxy paint. Protected aluminum is not sensitive
to wavelength, angle of incidence and polarization, so it useful for
