What Does Birefringent Crystal Mean?
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。Equally, the polarization point out of the laser beam inside a laser crystal with thermally induced birefringence is distorted. The sort of distortion is determined by the position, Because the birefringent axis has a varying (e.The birefr
