Abstract:
Dual-beam transient thermal lens studies were carried out in aqueous solutions of
rhodamine 6G using 532 nm pulses from a frequency-doubled Nd:YAG laser. The analysis of
the observed data showed that the thermal lens method can effectively be utilized to study the
nonlinear absorption and aggregation which are taking place in a dye medium.
