Ultrafast polarization

Ultrafast Polarizers

ARO offers thin film polarizers that have been designed to provide the top performance in Ti:Sapphire amplifiers. Multiple round trips in the amplifier have a multiplying effect on the characteristics of any optic in the cavity. The ARO sales team can offer a free estimate for custom thin film polarizers.

Close cooperation between the ARO design staff and leading researchers has led to the development of an advanced ultrafast polarizer, UV polarizer and a high energy polirizer. ARO’s polarizers are designed with an optimum combination of a high extinction ratio, spectral bandwidth, laser damage resistance, and minimal group delay dispersion. In addition to a broadband ultrafast polarizer, ARO can custom produce a wide selection of polarizers. Reach out to ARO’s sales team for a free quote and consultation.

TI:Sapphire Polarization

These high performance, thin film polarizers are coated to separate orthogonal polarizations with a high extinction ratio. They are designed for use over a broad spectral bandwidth centered on 800 nm. They are intended to be used at Brewster’s angle, and should be tilt tuned (±3°) to optimize performance.
