An ultrathin nonlinear optical (NLO) organic surface composed of numerous self‐assembled frustum‐shaped whispering‐gallery‐mode resonators displays both two‐photon luminescence and second‐harmonic‐generation signals. A super‐second‐order increase of the NLO intensity with respect to pump power confirms the microlasing action and practical usefulness of the NLO organic surfaces.
