Brewster's angle NLO crystals

For laser beam propagates from Air to NLO crystal (with refractiveindices n). Brewster's angle is defined as qB=arctan(n). At Brewster's angle, the surface reflectance is zero for the light with polarization inside the plane defined by the direction of light propagation and the normal to the surface.

In order to have a low surface reflection, Brewster's angle cut (B-cut) NLO crystals are used. Without special notices, Dream Lasers will fabricate the standard B-cut crystals according to the enclosed drawing. If customers design different sketch from our standard one, please notify Dream Lasers by giving us a drawing
