| 英文摘要 | nondiffracting optical beams play an important role in contemporary optics due to their special propagation characteristics, i.e., nondiffracting in a diffraction-free zone, shape recovering behind obstacles or self-healing property. liquid crystal spatial light modulators (lc-slm) are widely used for generating nondiffracting optical beams in virtue of programmable and dynamic features. in this paper, we propose a complex amplitude modulation technique that can encode any scalar complex fields for generating the complex nondiffracting beams. before experiment, the phase modulation curve of the phase-only lc-slm is optimized into being linear in a range of 0-2 pi by gamma correction in the way of variable binary phase gratings. then, we experimentally generate the nonaccelerating beams, e.g., two zero-order bessel beams with variable intensity distributions, and the nondiffracting petal-like beams generated by interfering with two coaxial bessel beams. by scanning a reflection mirror near the focal region along the optical axis, a stack of two-dimensional images is acquired, and then a three-dimensional intensity profile of the beam is reconstructed with a software. we also experimentally demonstrate a new kind of multi-main-lobe accelerating beam with parabolic accelerating trajectory by modifying the spatial spectrum of classical airy beam. compared with the so-called vectorial accelerating beam with multiple main lobes in spheroidal coordinates, our generated two-main-lobe accelerating beam has a very high energy efficiency. the self-healing property of the two-main-lobe accelerating beam is also demonstrated. the presented technique can generate a variety of complex nondiffracting optical beams rapidly and obtain their three-dimensional intensity distributions accurately, which has potential applications in the fields of optical microscope, optical date storage, optical trapping, optical micromachining, etc. |
