Ultrathin metasurfaces with record‐high nonlinear optical response of 1.2 × 10 6 pm V −1 for second harmonic generation are experimentally demonstrated in the mid‐infrared spectral range. A second harmonic power conversion efficiency of 0.075% is achieved in a 400‐nm‐thick ( λ /25) metasurface at a pump intensity of only 15 kW cm −2 .
