本文报道了一种能够补偿衍射光学元件（DOE）产生的近轴波场角色散的光学装置。示意性地，该系统是一个扩束器，其中插入了两个纯相位波带片，使耦合系统保持无焦。DOE，它引起一组连续的色散倾斜平面波，被放置在一个特定的位置内的建议设置提供一个输出光谱与消色差角偏差。证明了输出波包的相位波前和脉冲波前之间的方向匹配。
We report on an optical arrangement capable of compensating angular dispersion of paraxial wave fields developed by diffractive optical elements (DOEs). Schematically, the system is a beam expander in which two phase-only zone plates have been inserted, remaining afocal the coupled system. The DOE, which induces a continuous set of dispersive tilted plane waves, is placed at a specific position within the proposed setup providing an output spectrum with achromatic angular deviation. A directional matching between phase fronts and pulse fronts of output wave packets is demonstrated.
