? 2021 Elsevier B.V.The autofocusing Airy beams carrying a new kind of power-exponent phase are proposed and demonstrated experimentally in this paper. The physical mechanism of the proposed beams is theoretically analyzed by using energy flow and phase distribution. Moreover, the influence of the beam parameters on the light intensity distribution and orbital angular momentum is also discussed. The proposed Airy beams with new kind of power-exponent-phase vortices are expected to be useful for the extended applications of optical vortices, particularly for particle trapping.
