Getting My Birefringent Crystal To Work
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 because they are able to have their nonlinearity only by currently being non-isotropic, and that also will cause birefringence.The phrase anisotropy refers
