Difference‐frequency mixing of two pump waves can in principle excite two coherent phonon waves via the parametric process. Only when the phonon excitation is small can the nonlinear susceptibility of two‐phonon coherent anti‐Stokes Raman scattering be described as proportional to the product of two Raman tensors.
