Abstract
Measurement of optical absorbance is used to study the relaxation of a crylic film doped with Disperse Red 1 and poled with an electric field produced by the corona effect. Time variation of dichroism is studied over 10 days and results are adjusted with different time functions. Second-harmonic generation is presented as a test of the lack of symme try of the poled film resulting from the orientation process.
