LITTLE KNOWN FACTS ABOUT BIREFRINGENT CRYSTAL.

Crystal ingots, blanks, and polished and coated optical features made of birefringent crystals are supplied In line with your request.All nonlinear crystals for nonlinear frequency conversion are birefringent. It is because they are able to have their nonlinearity only by staying non-isotropic, Which also brings about birefringence.For propagation
