Abstract
Permanent modifications of the second-order nonlinear susceptibility χ(2)(−2ω;ω,ω) of certain Langmuir–Blodgett (LB) films can be induced photochemically by local irradiation with UV laser light, with the spatial resolution limited only by the laser spot size. In a LB film consisting of alternating monolayers of poly[N-(p-perfluorodecylsulfonylphenyl)-L-prolinol acrylate] and a ‘‘buffer’’ polymer, the kinetics of the laser bleaching process, as studied by optical second-harmonic generation, is found to be first order. The generation of a ‘‘χ(2)-grating’’ in the LB film is also demonstrated.
