Abstract
We have used pulses from a passively mode-locked dye laser (~1 psec, 5 kW) to study the reorientation of dye molecules dissolved in gelatine gels of concentrations from 2% to 10% gelatine. We have also used the Kerr effect to measure orientational dynamics of nitrobenzene (C6H5NO2) near the consolute critical point with n-hexane (C6H17). These measurements determine the local viscosity and interstitial pore size in the gel and the effect of critical fluctuations on molecular reorientation in binary critical mixtures.
