aims

Part 1: Nonlinear response at the microscopic level
- Fundamentals of Light-Matter Interaction
- Derivation of nonlinear susceptibilities using time-dependent perturbation theory
- Quadratic and cubic susceptibility, Kerr effect

Part 2: Nonlinear macroscopic response
- Different equations used for the description of nonlinear light propagation: Slowly varying envelope approximation, weak reflection approximation etc.
- Wave mixing: Second Harmonic Generation, Difference Frequency Generation
- Phase Matchting
- Propagation in media with Kerr nonlinearity: Self-phase modulation, self-steepening, spectral broadening of the pulse
- Optical phase conjugation,
- Nonlinear Schroedinger equation and temporal solitons in Kerr media
- Self-focusing: critical power and self-focusing length

Part 3: Current frontiers:
- Laser filamentation
- Electromagnetically induced transparency and Slow light
- High harmonic generation
- Above Threshold Ionization
