全息显示器用于数据存储、光捕获、安全、传感和光学设备中的应用。目前可用的全息制作技术仍然依赖于专业知识，成本高，耗时，限制了全息图的广泛个性化使用。发展高效、低成本的全息图快速制作技术是实际应用的需要。在这份报告中，我们使用一个单一的6纳秒的激光脉冲记录全息表面光栅烧蚀在良好的印刷油墨在基板上。整个全息图制作过程可以在几分钟内完成。所制备的全息图的光子学特征已被建模计算和实验表征。我们证明了我们的制造方法的多功能性，通过在光学透射和不透明表面上制备2D和3D全息图。我们预计，我们的策略，通过激光烧蚀制造全息图可能会在个性化的数据存储，光学和安全应用的巨大潜力。
Holographic displays are used for applications in data storage, light trapping, security, sensing, and optical devices. Currently available fabrication techniques for holography remain expertise-dependent, costly, and time-consuming, limiting the widespread personalized use of holograms. The development of efficient and low-cost techniques for the rapid fabrication of holograms is required for practical applications. In this report, we use a single 6 ns laser pulse to record holographic surface gratings by ablation in well-ordered printed ink on a substrate. The entire hologram fabrication process can be completed within a few minutes. The photonic features of the prepared holograms have been modeled computationally and characterized experimentally. We demonstrate the versatility of our fabrication method by preparing 2D and 3D holograms on both optically transmissive and opaque surfaces. We anticipate that our strategy to fabricate holograms through laser ablation may hold great potential in personalized data storage, optical, and security applications.
