Abstract
Nonlinear refraction of a new polymer structure based upon diglycidylether of bisphenol-A has been studied. The polymer contains 4-aminoazobensen as nonlinear optically active side groups covalently attached to each monomer unit. Thin dynamic grating writing and relaxation processes have been studied using frequency doubled YAG:Nd+3 laser ((lambda) equals 0.53 micrometers ). The dynamics of transient gratings was shown to have two different erasure times corresponding two different nonlinearity mechanisms fast one (relaxation time (3) equals 5 (DOT) 10-8 esu) and slow one (quasi-stationary). The later makes it possible to write and erase phase gratings reversibly by ns pulses. An analysis of possible mechanisms for refractive index nonlinear behavior in new structures is presented. In particular, a role of TRANS-CIS photoisomerization of the azo-compound in nonlinear optical properties of the structure are discussed.
