◄Lecture 2 - Nonlinear wave equation & Phase matching condition
►Tutorial n°1 - Three-wave mixing interactions
  • During this lecture, we will discuss the limits of the models presented in introduction. Reminding the relation between the linear suceptiblity and the impulse response of a linear medium, a tensorial description for the nonlinear susceptibilities will be provided. The constitutive relations of nonlinear optics will be demonstrated :
    P=\epsilon_0 \chi^{(1)} E + \epsilon_0 \chi^{(2)} E E + \epsilon_0 \chi^{(2)} E E E+\cdots

    The second part of the lecture the  properties of nonlinear susceptibility tensors will be presented in details, with a focus on their symmetry properties.
