High Energy Plate Polarizers

High-energy plate polarizers separate s and p polarizations with an extinction ratio (Tp/Ts) of greater than 10,000:1 in the transmitted beam and transmission (Tp) of up to 99%. Thus, they are ideal for intracavity or extracavity high-power applications where fluences are greater than 500 mJ/cm2 and calcite or cemented cube polarizers cannot be used.

Our thin-film plate polarizers achieve superior high-power performance and guaranteed transmission at a specific angle of incidence, with no angle tuning required. By combining dielectric IBS coatings with fused silica substrates, we produce stable components that are easy to align and exhibit high laserdamage thresholds in both reflection and transmission.
