RUMORED BUZZ ON 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 might have their nonlinearity only by being non-isotropic, Which also causes birefringence.For propagation alongside the optical axis, the elec
