Abstract
The dual-beam (pump, probe) time-resolved Z-scan technique is used to study the thermal changes in refractive index that are due to one- and two-photon absorption in organic solvents. The time resolution enable d us to select a pure thermal signal and to measure absolute variation s as small as 10(-6) that were due to heating. Gaussian approximation was used for the pump and probe beams to fit experimental and calculat ed model dependencies.
