Optical beam propagation in biaxial crystals
WebBeam propagation in anizotropic crystals ... An uniaxial crystal is isotropic within the plane orthogonal to the optical axis of the crystal. A crystal which has only two optic axis is called biaxial crystal. The refractive index of the ordinary ray is constant for any direction in the crystal, and of the extraordinary ray is variable and ...
