The Nonlinear Optical Susceptibility
... In Section 1.3 we show how to treat the vector nature of the fields; in such a case χ (1) becomes a second-rank tensor, χ (2) becomes a third-rank tensor, and so on. In writing Eqs. (1.1.1) and (1.1.2) in the forms shown, we have also assumed that the polarization at time t depends only on the insta ...
