Abstract

Simultaneous writing and probing of photoinduced second-order susceptibility χ2 in an azo-dye polymer thin film is demonstrated. The method is based on the fact that tensor properties of χ2 provide different planes of polarization for seeding and signal second harmonics. Our technique allows the χ2 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 χ2 in a DR1-PMMA guest–host system under low seeding intensities is shown.
