Optical beam propagation in biaxial crystals
WebOptical beam propagators are derived from the Maxwell wave equation for a refractively biaxial medium. The propagators carry fields polarized nearly parallel to the fields of their … 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

Optical beam propagators are derived from the Maxwell wave equation for a refractively biaxial medium. 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 …
