Brewster Windows are uncoated substrates of laser grade surface quality and parallelism that are designed to be used at Brewster’s Angle (the angle at which p-polarized light incident on the surface is not reflected). At this angle, p polarization reflectance drops to zero. When used in a laser cavity, a Brewster Window reduces the cavity loss for p-polarized light compared to s-polarized light. The result of preferentially reducing the loss along one polarization axis is that the laser will emit linearly polarized light.
