Thin Film Laser Polarizers (Round) can be used as extracavity attenuators for Nd:YAG laser fundamental and its harmonics or intracavity Q-switch hold-off polarizers.

Thin Film Laser Polarizers (Rectangular) provide the achievement of strictly linear polarization of laser radiation and utilise the polarization which occurs on reflection from a plane surface.
Zero order plates are comprised of two different plates cut parallel to their optical axis. They are temperature insensitive. High quality AR coatings are applied.
Zero Order Air-Spaced Wave Plates are used for high power laser applications. Wavelength is 1064 nm, 532 nm, 355 nm or 266 nm.

Low order plates are suitable for high and low power applications. These plates are less temperature sensitive and temperature dependent than multiple order plates.
Multiple order plates are made from a single crystalline plate. The thickness of it is 1-1.5 mm. High quality AR coatings are applied.

Dual wavelength multiple order waveplates are offered for Nd:YAG harmonic wavelengths and can be used to separate the harmonic beams by means of a change in their state of polarization.
As compared to a waveplate, a rotator has an intrinsic advantage of being independent of rotation around its own optical axis. A polarization plane rotator is normally used for the specific wavelength.
