Empirical correction of geometrical model expression of two-photon absorption
Using a comparative fluorescence method, two-photon absorption cross-section for a number of common laser dyes were measured. It was found that the two-photon absorption cross-section does not follow Schafer-Schmidt s geometrical model expression for most dyes. A simple empirical correction of Schafer-Schmidt s expression is proposed. The experimental results are compared with the value predicted by corrected expression and good agreement is obtained.
