Abstract: We propose an novel optical element-liquid axicon-to generate self-imaged bottle beams in this paper. From the diffraction theory combined with geometrical optics the light field behind the liquid axicon is analyzed, and the result shows that when the refractive index of infused liquid is smaller than that of the axicon material, it can produce self-imaged optical bottle beams. Through simulation with software MathCAD, we obtain the conversion process of a complete self-imaged optical bottle beam cycle and the evolution process of the bottle beam. We find that the coherent length of self-imaged bottle beams generated by liquid axicon is adjustable. In this paper, we analyze how to use self-imaged bottle beams to capture the particles, and the advantages of capturing multilayer particles using self-imaged bottle beams are also discussed.
