NON-LINEAR OPTICS

Electromagnetic description of materials – a review.

Non-linear dependence of P(E). Nonlinear wave equation, source term. Brief mention to the Born approximation.

2nd order materials: Second Harmonic Generation, Rectification; sum and difference of frequencies.

Interaction of a second order material with a monochromatic wave (with or without a static term), and with two monochromatic waves. Electrooptics in the context of nonlinear optics.

Introduction to phase matching, in relation to the conservation laws of energy and linear momentum.

Examples.
