Abstract
The thermal lensing technique is applied to study two-photon absorptio n of dye molecules in organic solutions. With the use of a differentia l two-cell thermal lens spectrometer, the contribution due to one-phot on absorption by solvent molecules is suppressed. Observed power depen dence of the thermal lensing signal confirms the two-photon character of the absorption process.
