Using ultraviolet femtosecond pulses with high irradiance stability, we measured the two-photon absorption (TPA) coefficients in a number of substances with a total accuracy of ∼10%. Six commercial fused-silica samples (KU-1, Corning 7940, SQ, Suprasil, Herasil, and Infrasil) possess TPA coefficients (β values) of ∼2 × 10-11 cm/W. For crystalline quartz and sapphire, the following β values were obtained: (1.2 ± 0.2) × 10-11 and (9.4 ± 1.2) × 10-11 cm/W, respectively. In β-barium borate crystal the TPA coefficient depends on crystal cut, beam polarization, or both and varies from (47 ± 5) × 10-11 to (68 ± 6) × 10-11 cm/W. For eight liquids that were studied (water, heavy water, ethanol, methanol, hexane, cyclohexane, 1,2-dichloroethane, and chloroform) the β value lies from (34 ± 3) × 10-11 to (95 ± 11) × 10-11 cm/W.
