WebBiaxial crystals have two optic axes. • The acute angle between the two optic axes in biaxial crystals is called the indicatrix 2V. For biaxial positive crystals, the acute angle is centered on Z and the acute 2V is 2V γ For biaxial negative crystals, the acute angle is centered on X and the acute 2V is 2V α WebThis paper investigates theoretically and numerically the propagation characteristics of a circular Airy beam (CAB) in a uniaxial crystal in detail. The beam loses its boundary cylindrical symmetry during propagation because of the medium anisotropy, although it propagates along the optical axis. This effect of anisotropy on the propagating beam …
