Round Thin Film Laser Polarizers
- provide the achievement of strictly linear polarization of laser radiaton
- utilize the polarization wich occurs on reflection from a plane surface
- high damage threshold reaching 10 J/cm2
- extinction ratio 200:1
Thin Film Polarizers separate the s- and p-polarization components. They are designed for use in high energy lasers. Due to high damage threshold, reaching 10 J/cm2 @ 1064 nm 8 ns, Thin Film Polarizers are used as an alternative to Glan laser polarizing prisms or cube polarizing beamsplitters.
Typical applications are intracavity Q-switch hold-off polarizer or extracavity attenuator for Nd:YAG lasers.
Thin Film Polarizers can be used at an > 40° angle of incidence, but polarization is most efficient and appears in a broad wavelength range at 55° AOI (Brewster angle). Typical polarization ratio Tp/Ts is 200:1.
Standard size is up to Ø50 mm (2”), while max. available dimensions are 100×200 mm. For optimal transmission a Thin Film Polarizer should be mounted in an appropriate holder for angular adjustment.
