The theory and application of nondiffracting beams is one of the most important topics in various optical fields. In 1979 Berry and Balazs made an important observation within the context of quantum mechanics: they theoretically demonstrated that the Schrodinger equation describing a free particle can exhibit a non-spreading Airy wave packet solution. After Siviloglou observed Airy beams experimentally in 2007, Airy beams appears as a new member of non-diffracting beams family in very recent years. In order to explore the potential of Airy beams in the traditional optical systems, its features and applications are studied. In this paper, we design the diffractive optical elements to modulate the phase of the beam and produce the uniform dot array beam based on the Airy beam. We analyze the optical characteristic of Airy beams and the dot array beam. Numerical simulations and optical experiments are performed, and the results are in good agreement with each other. The uniform and the non-diffraction of the modulated beams are analyzed and the results are promising. It is believed that this study will provide useful information for further applications and productions of various Airy beams in optical systems, and it is could be widely applied in operating and focusing at multi-particles or cells for optical tweezers.
