Surprisingly, we find that the largely detuned driving laser can improve the scaling of cavity squeezing from $S^-2/5$ to $S^-2/3$, where S is the total atomic spin. Moreover, we also demonstrate that the experimental imperfection of photon scattering into free space can be efficiently suppressed by detuning.
