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.
