5 Tips about Birefringent Crystal You Can Use Today
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's because they will have their nonlinearity only by currently being non-isotropic, and that also leads to birefringence.Intrinsic birefringence could be the exp
