Brewster windows are uncoated windows used at Brewsters Angle (the angle at which only
p-polarized light has zero transmission loss). A series of Brewster Windows used in a laser cavity
will ensure linearly polarized output light. Brewsters Angle can be calculated from
the following equation: TB = tan-1 (n2 /n1)
