✦ Synopsis

We report the observation of sub-picosecond oscillatory signals during pump-probe studies of silica glasses. The behaviour of these oscillations is characteristic of impulsive stimulated Raman scattering. We demonstrate that these oscillations can be large enough to interfere with transient absorption experiments when silica cuvettes are used to retain the sample, and are potentially a cause of artifactual interference.
