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。The polarization dependence of your refractive index can have many different outcomes, a number of which happen to be remarkably important in nonlinear optics and laser engineering:For an arbitrary angle θ in between propagation path and
