Abstract
We introduce Pearcey Gaussian beams with the astigmatic phase (APPGBs) for what we believe is the first time and study their propagation in the chiral medium. APPGBs are split into the left and the right circularly polarized beams (LCP-APPGBs and RCP-APPGBs), of which we derive the analytical expression under the paraxial approximation. The results show that RCP-APPGBs have a longer autofocusing distance, which we can alter by adjusting the rotating factor or the chiral parameter. Besides, the increase of the rotating factor leads the autofocusing distances of both LCP-APPGBs and RCP-APPGBs to increase, while the increase of the chiral parameter leads to opposite effects on LCP-APPGBs and RCP-APPGBs. During propagation, the rotating factor can rotate the transverse intensity distribution, changing the rotation angular velocity. In addition, the rotating factor has a great impact on the phase distributions. Last, the effects of the rotating factor and the chiral parameter on the gradient force and the scattering force are analyzed.
