This paper investigates the propagation properties of the odd-Pearcey Gaussian beam (OPGB) in a parabolic potential. It is found that, in addition to auto-focusing at the focal plane, the OPGB unexpectedly performs weak off-axis focusing. By choosing an appropriate parabolic parameter, the focusing distance and focal intensity can be adjusted.
In this paper, the propagation properties of the odd-Pearcey Gaussian beam (OPGB) in a parabolic potential are investigated analytically and numerically. Except for the auto-focusing at the focal plane, the OPGB performs a weak off-axis focusing unexpectedly. The focusing distance and the focal intensity can be adjusted by choosing an appropriate parabolic parameter. Also, the Poynting vector of the OPGB is demonstrated. In addition, we investigate the radiation forces of the OPGB and find that the trapping points can be generated during propagation. (C) 2021 Optical Society of America
