Abstract
Recently we reported1,2 on a technique for measuring the decay of the second order optical susceptibility χ(2) as a function of temperature and pressure in poled nonlinear optical (NLO) polymeric materials. This approach utilizes second harmonic generation (SHG) to monitor the rotational reorientation of the NLO chromophores in such systems and yields structural information directly related to the reorientation process in poled polymers.
