Not known Facts About 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 from the refractive index can have a variety of consequences, several of that are hugely vital in nonlinear optics and laser technology:The birefringence of nonlinear crystal materials allows for birefringent se
