4Lasers unmounted polarizing cubes are fabricated from two identical right-angle prisms with their hypotenuse faces adhered together via optical contact or epoxy glue. Polarized cubes are designed to transmit p-polarized light with minor deviation (<3 arcmin) and deflect s-polarized light by 90° angle. Prior to cementing polarizing dielectric thin-film coating is applied onto one of the prisms hypotenuse faces, while input and exit surfaces are anti-reflective coated for a particular wavelength range. 4Lasers optically contacted polarizing cubes provide a higher laser-induced damage threshold, therefore are primarily used for high-power applications, while epoxy glued cubes are a cost-effective choice for low and mid-power applications. We recommend using these elements with collimated laser beams in order to avoid beam aberrations.
