Brewster Windows are
uncoated substrates which are used as polorizers, typically
within a laser cavity. Positioned at Brewster's Angle
the P-Polarization portion of the light will pass through
the window with no losses while the S Polarization portion
will be reflected off the brewster window. Used in a laser
cavity the brewster window is essentially a polorizer.
Brewster's Angle is calculated from:
¦È= tan-1(n)
where ¦È is Brewster's Angle and n is the refraction index
of the material.
