Evaluation of the second harmonic coefficient and stablility investigation in poled polymer films
A detailed procedure for evaluation of second harmonic coefficient d33 in Poled polymer films was given and temporal stability investigstion in such system was discussed. The apparent energy of activation for relaxation from oriented to random state in DANS doped polymer was estimated. A concept of optimum incidence angle θm was introduced and the possible connection between the magnitude variation in θm during the relaxation process and the temporal stability is also dicussed.
