The authors regret that errors occurred in the following paragraph of the above article. Also, the following reference was omitted. The correct reference and paragraph are printed below: ‘‘In the semi-classical formulation of stimulated RS, the interaction between the light and a single non-degenerate mode of the vibrational field is given by the phenomenological potential V = NvcSklRklEkElQ/2. Here, N is the number of cells, vc is the cell volume, Eu(t), is a component of the electric field at time t, Q is the phonon coordinate, Rkl c Bvkl/BQ is the Raman tensor, and vkl is the linear susceptibility. Let V0 be the phonon frequency corresponding to a wavevector near the center of the Brillouin zone. Pk ¼ ¨ þ Q

Within the harmonic approximation, V leads to coupled phonon – photon field equations of the formin which a single tensor is used to describe both the nonlinear part of the polarization P and the force F driving the oscillator. These expressions are rigorously valid only if Rkl does not depend on frequency, but they can be modified without difficulty to account for dispersion’’ [12].
