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 face, while input and exit surfaces are antireflective coated for particular wavelength range. 4Lasers optically contacted polarizing cubes provide 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 to use these elements with collimated laser beams in order to avoid beam aberrations.
