We report experimental values of the group velocity dispersion (GVD) of water and methanol at 800 nm. We find GVDwater 800 = (25.71± 0.5) fs2 mm−1 and GVDmethanol 800 = (33.56±0.5) fs2 mm-1. These were measured by sending 50 fs, 800 nm pulses with various amounts of chirp through a glass cell filled with a solution of fluorescein in these solvents and recording the production of visible light from the side using a commercial digital camera. This simple setup also gives quantitative information on the duration of our pulses and lets us check independently the correct operation of our grating-based pulse compressor. Results are compared to FROG measurements.
