Everything 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。Likewise, the polarization point out of the laser beam in a laser crystal with thermally induced birefringence is distorted. The kind of distortion will depend on the place, Considering that the birefringent axis incorporates a different (
