“…The values of nonlinear refractive index (n 2 ) for PThOxad1a-c were found to be of the order of 10 -10 esu, and they are nearly two orders larger than the n 2 values reported for thiophene oligomers (Hein, 1994). The χ (3) values of PThOxad 1a-c are comparable with 5x10 -12 esu, reported for poly(3-dodecyloxymethylthiophene) (PDTh) (Bredas & Chance, 1989).…”

The thermal stationary nonlinear refraction is determined with enhanced sensitivity by measuring the profile distortions of a cw probe light beam in the presence of absorption of a collinearly propagating pump light beam. By measuring the total profile distortion of the probe beam for different position of the sample cell, a signal similar to the well-known Z-scan signal is obtained. Using the Gaussian decomposition method a simple formula is deduced which relates the induced thermal phase shift to the magnitude of the observed signal. Phase shifts as low as λ/40000 with a signal-to-noise ratio of unity becomes detectable with this technique.
