Propagation dynamics of a circular Airy beam in a uniaxial crystal

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 WebBiaxial crystals, as their name indicates, have two optic axes along which light is propagated with the same velocity.
