The 2-Minute Rule for Magneto-Optical 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. This is due to they could have their nonlinearity only by getting non-isotropic, and that also will cause birefringence.Intrinsic birefringence could be the term u
