The material in the center of the cover image is SnSe, with highly anisotropic in‐plane structure, and two incident laser beams, with polarizations perpendicular to each other, propagate through SnSe. As the cover image illustrates, the saturable absorption (SA) and pump‐probe responses are strongly polarization‐dependent, consistent with the linear absorption results. Furthermore, the anisotropic SA effect has excellent potential for novel all‐optical switches based on the switching light polarization.
