The Basic Principles Of Birefringent Crystal
各向异性透明晶体如方解石、石英等的折射率，是其固有的特性，称为永久双折射。All nonlinear crystals for nonlinear frequency conversion are birefringent. It is because they might have their nonlinearity only by being non-isotropic, Which also leads to birefringence.The polarization dependence with the refractive ind
