Brewster Plane-parallel Crystal

Brewster crystal is characterized by its length L and index of refraction n. A beam falls at the face of the crystal at Brewster’s angle. Element’s length is measured along the beam path.

One can consider this element as a rod whose opposite ends are cut at Brewster’s angle. It is a widely used form of laser gain medium.
