Abstract

The thermal lens properties of Oxotrichlorobis(triphenylphosphine) rhenium(V) solution were explored using the dual-beam CW laser (pump-probe beams) z-scan. Then, a numerical model utilizes to performed theoretical calculation in order to determine the thermal lens parameters such as: θ, dn/dT, D, tc and Peclet Number (PE). Our results have shown that the time constant tc , θ and peclet number PE are very sensitive to the input pump laser power, with the increasing of the input laser powers, the tc and Peclet number PE have decreased, while the θ has increased as the result of laser power increase..
