Limitations Arising from Two-Photon Absorption of Solvent in Pulsed-Laser Thermal Lens Detection: Determination of the Two-Photon Absorption Coefficient of Ethanol at 266 nm

Abstract

Two-photon absorption of the solvent under pulsed-laser excitation at 266 nm produces a high background thermal lens signal interfering with the analyte signal. Discrimination of both solvent and analyte signals along with calibration of the photothermal response has allowed the determination of the two-photon absorption coefficient of ethanol. The obtained value, 3.0 × 10<sup>−10</sup> cm W<sup>−1</sup>, is close to the literature values obtained from transmittance measurements using picosecond or femtosecond laser pulses.
