Glan-Laser Polarizer is a Glan-Taylor Polarizer that is specifically designed to deal with high-energy laser light. Glan-Laser polarizers are manufactured from select calcite, a-BBO, YVO4 crystals that must pass a laser scattering sensitivity test. Glan-Laser polarizers are ideal for applications requiring extremely high polarization purity, high damage threshold, and a broad wavelength range. Two polished side exit ports are provided to allow bidirectional use of the glan-laser polarizer. These side ports also ensure that the rejected light from high power lasers can safely exit the glan-laser polarizer.
YVO4 Glan-Laser Polarizer with near Brewster's angle cut have superior polarization of the reflected beam and higher damage threshold. YVO4 Glan-Laser Polarizer is good for using as high power laser polarization beam splitter or combiner. a-BBO Glan-Laser Polarizer has highest damage threshold with UV laser, 200-2200 nm.

High Transmission Glan-Laser Polarizers are altered Glan-Taylor Polarizer with Brewster angle cut prism interface for max transmission of high power laser. Two side exit windows are polished to allow bidirectional use of the glan-laser polarizer. High Transmission Glan-Laser Polarizers are used where high transmission is needed such as Q-switch and laser cavity dumping.
