Thin Film Polarizers separate the s- and p-polarization components. They are designed for use in high energy lasers. Due to a high damage threshold, reaching 10 J/cm2 @ 1064 nm 8 ns, Thin Film Polarizers are used as an alternative to Glan Laser Polarising Prisms or Cube Polarising Beamsplitters.
Typical applications are intracavity Q-switch hold-off polarizer or extracavity attenuator for Nd:YAG lasers.
For optimal transmission Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment.
Provide the achievement of strictly linear polarization of laser radiaton
Utilize the polarization wich occurs on reflection from a plane surface
Rs/Tp:>99.5/95.0% for standard thin film polarizers
Rs/Tp:>99.5/99.0% for high transmittance thin film laser polarizers
Ts<0.2%, Rp<0.2% for ultra high transmission thin film polarizers
Tp>98%, Ts<0.1% for thin film polarizers with high extinction ratio
High damage threshold reaching 10 J/cm2
Extinction ratio 200:1 (for standard, high and ultra high transmission thin film polarizers), 1000:1 (for thin film polarizers with high extinction ratio)
