Abstract
The action of UV radiation on polymeric materials that contain the precursors of
gold and hybrid organic–inorganic materials based on titanium oxide has been
studied. It is shown that the changes of the absorption spectrum in the visible range
are accompanied by a significant change of their linear and nonlinear optical properties
in the IR region. The method of spectrally resolved two-wave mixing of femtosecond laser
pulses was used to determine the rapid electronic cubic optical susceptibility in the IR
part of the spectrum. The values found for the nonlinear refractive index exceed the
value for quartz by a factor of 100–300. The change of the linear refractive index
is determined from the diffraction efficiency of thin diffraction gratings formed under
the action of UV to be at the 10<sup>−4</sup>–10<sup>−5</sup>
level.
