Product Description

Brewster Window are uncoated substrates that are designed to be used at Brewster's Angle (the angle at which p-polarized light incident on the surface is not reflected). Brewsterâ„¢s Angle is given by the following formula: 

B = tan-1(n) 

Here, B is Brewster's Angle and n is the index of the reflection of the material. 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.
