Controlling of Acceleration Trajectory of Airy Beams in Large Range Based on Holographic Printing
Based on the diffraction theory and the definition of Airy function, a trajectory expression of the intensity peak of Airy beam is deduced theoretically when the central position of cubic phase mask deviates from optical axis of Fourier transform lens, and the influence of the initial launch angle on the acceleration trajectory of Airy beam is discussed. We find that when the lateral acceleration is a constant, the larger the initial launch angle is, the larger the initial launch angle changing is. In order to increase the initial launch angle, we manufacture cubic phase mask with big size using computer-generated hologram microfilming printing system. Accelerating Airy beams are generated with the phase mask, and the propagation trajectory of Airy beam can be controlled within a large range when the dislocation between the center of phase mask and optical axis of Fourier transform lens is changed.
