NON-LINEAR OPTICS

2^nd order phenomena: frequency conversion, optical parametric amplification and oscillation, Spontaneous Parametric Down Conversion (and generation of entangled photons).

Phase matching: energy and momentum conservation in dispersive materials; using uniaxial materials for SHG. Overview of types of phase matching, in relation to the polarization of the signal, idler and pump waves.

Basics of coupled wave theory and overview of results for 2^nd order nonlinear phenomena.

Third order materials and nonlinear optical effects: typical values of the nonlinear coefficient; third harmonic generation; self-phase modulation, Kerr effect, filamentation.
