Nanolaminates composed of alternating layers of ZnO and Al 2 O 3 are grown by conformal atomic‐layer deposition. Their structural and nonlinear optical properties are correlated. Optimized nanolaminates exhibit an effective bulk second‐order nonlinear optical susceptibility that is independent of the substrate and that is five times larger than that of potassium dihydrogen phosphate.
