Thermal Lens Effect

Two-photon absorption spectrum of aniline is recorded using thermal lens effect with optical parametric oscillator as the pump source. Studies show that the two-photon absorption spectrum observed corresponds to 1A1 → 1B2 transition of aniline.

The thermal lensing technique is applied to study two-photon absorption of dye molecules in organic solutions. With the use of a differential two-cell thermal lens spectrometer, the contribution due to one-photon absorption by solvent molecules is suppressed. Observed power dependence of the thermal lensing signal confirms the two-photon character of the absorption process.

Dual beam transient thermal lens studies were carried out in rhodamine 6G methanol solutions using 532 nm pulses from a frequency doubled Nd:YAG laser. Analysis of thermal lens signal shows the existence of different nonlinear processes like two photon absorption and three photon absorption phenomena along with one photon absorption. Concentration of the dye in the solution has been found to influence the occurrence of the different processes in a significant way.
