Surpassing the diffraction limit in long-range laser engineering via cross-scale vectorial optical field manipulation:perspectives and outlooks
简介：We present a vectorial optical field(VOF)framework that surpasses the diffraction limit in both long-range imaging and energy delivery.By jointly engineering spatial and temporal dimensions,reflective Fourier ptychography is extended to 3.2 km with 0.37×the classical diffraction limit,while a single-photon LiDAR tomography system achieves centimeter-scale,sub-diffraction imaging at 3.3 km using superconducting nanowire single-photon detectors.These advances demonstrate super-resolution,turbulence-resilient imaging over kilometer-range distances.Beyond super-resolution opti-cal,high power VOFs are able to counteract thermal blooming during atmospheric laser propagation,enhancing on-tar-get power density by a factor larger than 2.Together,these results may outline a cross-scale paradigm that links high-power vector-field structuring,single-photon detection,and adaptive control—offering a pathway toward next-generation optical systems that integrate imaging,sensing,communication and directed energy within a common physical framework.展开
