◄Lecture 3 : Nonlinear susceptibilities & Constitutive relations of nonlinear optics
►Lecture 4 : 2nd order nonlinear interactions (PART 1)

  • This tutorial concerns the generation of a sum-frequency beam after the propagation of two linearly polarized beams through a 2nd order nonlinear material, and in a second part the efficiency of the second-harmonic generation effect (under the undepleted pump approximation).

    By the end of this activity, students will be skilled at ...

    •S3 - Solving the nonlinear equation in parametric situations and derive analytical solutions under the undepleted pump approximation
    •S4 - Calculating nonlinear interaction performances/efficiencies in situations governed by analytical solutions or expressions

    By the end of this activity, students will start to understand  ...

    • U3 - Nonlinear interactions lead to energy transfer between optical beams, and/or between matter and beams, enabling in some cases the realization of nonlinear optical amplification and/or oscillation.

    U4 - Nonlinear optics is an essential tool to create novel optical frequencies generated through the interaction of incident beams within nonlinear materials


    By the end of this activity, students will start to be able to  ...

    •T1 - Model any 2nd or 3rd order nonlinear effects, including numerical simulations
    •T2 - Evaluate nonlinear interaction performances/efficiencies under approximations that should be specified, explained and justified
