Highly efficient and programmable writing of multidimensional optical data is of great value for next‐generation high‐throughput information technologies but has been rarely achieved. Here, a one‐step frame printing of chromatic pixels in lithium niobate crystal by using a single ultrafast laser pulse is reported. In this strategy, a phase superposition‐based spatial light modulation strategy is applied to split a single ultrafast laser pulse into multiple son pulses with designated optical properties and spatial distribution patterns. It is demonstrated that these son pulses allow for massively creating micro‐amorphous phase transition zones with on‐demand structural features that can modulate the intrinsic birefringence of the crystal matrix and generate wavelength‐selective interference in the visible band to form pixel‐level chromatic patterns, namely, single‐pulse‐driven frame color printing. The created chromatic pixels can be encoded into computer‐recognizable data arrays to play a role in high‐efficiency multidimensional information recording. The presented approach enables fast and programmable information batch writing in 3D space and can serve as a versatile tool boosting next‐generation information optics.

铌酸锂晶体中彩色像素的单脉冲驱动帧打印

多维光学数据的高效和可编程写入对于下一代高通量信息技术具有重要价值，但很少实现。在这里，报道了使用单个超快激光脉冲在铌酸锂晶体中进行彩色像素的一步帧打印。在该策略中，应用基于相位叠加的空间光调制策略将单个超快激光脉冲分成具有指定光学特性和空间分布模式的多个子脉冲。事实证明，这些子脉冲允许大规模创建具有按需结构特征的微非晶相变区，可以调制晶体基质的固有双折射并在可见光波段产生波长选择性干涉，以形成像素级彩色图案，即单脉冲驱动帧彩色打印。创建的彩色像素可以被编码成计算机可识别的数据阵列，以在高效的多维信息记录中发挥作用。所提出的方法可以在 3D 空间中实现快速、可编程的信息批量写入，并且可以作为促进下一代信息光学的多功能工具。
