An introduction to nonlinear optics (NLO) and the major challenges in the field of NLO‐properties of polymeric materials, is given in this paper. Methods for the investigation of nonlinear optical properties of [4‐(2‐methacryloxyethyl)methylamino]‐4′‐cyanoazobenzene copolymers with methyl methacrylate (MMA) are demonstrated: Electric Field Induced Second Harmonic Generation (EFISHG), Hyper Rayleigh Scattering (HRS), Second Harmonic Generation (SHG) in floating monolayers and SHG in poled polymer films. An example of phase‐transition analysis by SHG is given.
