G. Sheeren et al., NONLINEAR-OPTICAL PROPERTIES OF POLYMERS AND THIN POLYMER-FILMS, Die Makromolekulare Chemie. Macromolecular symposia, 69, 1993, pp. 193-203
An introduction to nonlinear optics (NLO) and the major challenges in
the field of NLO-properties of polymeric materials, is given in this p
aper. Methods for the investigation of nonlinear optical properties of
-methacryloxyethyl)methylamino]-4'-cyanoazobenzene copolymers with me
thyl methacrylate (MMA) are demonstrated : Electric Field Induced Seco
nd Harmonic Generation (EFISHG), Hyper Rayleigh Scattering (HRS), Seco
nd Harmonic Generation (SHG) in floating monolayers and SHG in poled p
olymer films. An example of phase-transition analysis by SHG is given.
