The single-mode and multimode free-running dye lasers are examined as possible sources for generating power-squared corrected two-photon absorption spectra. The observed differences between the two sources is attributed to the presence of mode noise in the multimode output, which yields inaccuracies in spectra when used as a source for two-photon spectroscopy. Using an accurate reference spectrum generated with the single-mode source, the utility of ratioing to obtain accurate spectra with the multimode laser is demonstrated. Alternate techniques for obtaining power-squared corrected two-photon spectra with the multimode laser are considered.
