We describe a sensitive method for measuring time-dependent changes in refractive index within ~5  µm of an interface using off-null time-resolved ellipsometry and a dual-cavity femtosecond laser. The sensitivity to changes in refractive index is two orders of magnitude higher than conventional picosecond interferometry. A thin metal film on a sapphire substrate is heated by ~10  K using an ultrafast optical pump pulse; the subsequent changes of the phase difference deltaDelta between p-hat and s polarized reflectivity are tracked using off-null ellipsometry using a time-delayed probe pulse. We demonstrate a sensitivity of deltaDelta[approximate]3×10−7  deg/[square root of]Hz using interfaces between Au and water, and Au and various gases including R134a, a common refrigerant. Our data for the damping rate of [approximate]200 MHz frequency acoustic waves in O2, N2, and Ar at atmospheric pressure agree well with prior results obtained at much lower pressures and frequencies. ©2010 American Institute of Physics
