摘要: The propagation dynamics of a chirped Airy vortex (CAiV) beam with x-polarization in uniaxial crystals orthogonal to the optical axis is studied analytically and numerically. The effect of the ratio of extraordinary and ordinary refractive indices, the chirp parameter, as well as the propagation distance is analyzed, which shows that the focused position of the CAiV beams can be controlled through changing the ratio of the extraordinary and ordinary refractive indices. In addition, with the propagation distance increasing, the asymmetry of the intensity and the angular momentum of the CAiV beam during propagation becomes much more visible. The variation of the chirp parameters can change the attenuation velocity of the vortex as well.
