They are designed for use in high energy lasers. Due to high damage threshold, reaching 10 J\/cm2\u00a0@ 1064 nm 8 ns, Thin Film Polarizers are used as an alternative to Glan Laser Polarizing Prisms or Cube Polarizing Beamsplitters.<\/p>\n<p>Typical applications are intracavity Q-switch hold-off polarizer or extracavity attenuator for Nd:YAG lasers.<\/p>\n<p>Thin Film Polarizers can be used at an &gt; 40\u00b0 angle of incidence, but polarization is most efficient and appears in a broad wavelength range at 56\u00b0 AOI (Brewster angle). Typical polarization ratio Tp\/Ts is 200:1.<\/p>\n<p>Standard size is up to \u00d850 mm (2\u201d), while max. available dimensions are 100\u00d7200 mm. For optimal transmission a Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment.
