Abstract

Azo-dye-doped polymers have a large intensity dependent refractive index with at least two mechanisms that are characterized by their response times and by the sign of amplitudes. τ₁ is in a range of 700ms to 900ms and τ₂ in a range of 50s to 60s. To charcterize the dynamics of the real and imaginary part of this response, we use a T-scan technique(using open and closed apertures), where the intesity dependent focusing/defocusing processes of the material is studied as a function of time.
