Abstract
Simultaneous writing and probing of photoinduced second-order susceptibility in an azo-dye polymer thin film is demonstrated. The method is based on the fact that tensor properties of provide different planes of polarization for seeding and signal second harmonics. Our technique allows the value to be monitored in real time, completely eliminating the distortion of optical poling that can occur in traditional probing configurations. The possibility of attaining high values of in a DR1-PMMA guest–host system under low seeding intensities is shown.
