High Power Polarisers

Polarisers are used to separate s-pol and p-pol light. We offer a large variety of designs.

Plate polarisers and cube polarisers made of different materials suited for high power applications are available.

Thin Film Polarisers

Thin film Polarisers and broadband polarisers to separate polarization.

High Power Polarisers

Thin film polarisers are used in polarization separation. They are especially well suited for high power levels and UV wavelengths.

 

Broadband plate polarisers with low dispersion are particularly well-suited for polarization separation of broadband systems such as Ti:sapphire fs lasers.

Thin film polarisers are used in polarization separation. They are especially well suited for high power levels and UV wavelengths.

When using and assembling thin film polarisers, it is important to note that the p-polarized beam is slightly offset and that the s-polarized beam is deflected by ≈ 112°.

 

Working principle

Thin film polarisers are assembled at the Brewster angle ≈ 56°. An anti-reflection coating on the rear side is not necessary; the polariser can only be used in one direction along the optical axis. Due to the TFP coating on the front side a good extinction ratio can be achieved.

These polarisers are manufactured using an IAD process. In addition, the coating process for these polarisers is supervised using a broadband monitoring technique. The result is a high power thin-film polariser that can be used at any angle from 53° to 59°. Available wavelengths range from 450 nm to 1064 nm.

One major advancement is the improved specifications for significantly higher transmission and reflection values. More information can be found in our datasheet.

Broadband plate polarisers with low dispersion are particularly well-suited for polarization separation of broadband systems such as Ti:sapphire fs lasers. They are coated on both sides and can therefore be used in dual directions. During development and assembly, it is important to keep in mind that the p-polarized beam is slightly offset and that the s-polarized beam is deflected by ≈ 144°.

The coating for broadband plate polarisers has been optimized for low dispersion, similar to the previous coatings.

Working principle

The plate polarisers are assembled at an angle of ≈ 72° to the incident beam.
