MAGNETO-OPTICAL CRYSTAL - AN OVERVIEW

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 can have their nonlinearity only by being non-isotropic, and that also results in birefringence.The polarization dependence of your refractive in
