Abstract

In this paper we present the first results concerning the Third Harmonic Generation (THG) for thin films of functionalized alkynyl ruthenium based chromophores. This approach allowed us to determine the electronic contribution of the third-order nonlinear optical susceptibility <3> elec χ of these chromophores and to investigate three theoretical models (Reintjes model, Kubodera and Kobayashi model, and Kajzar and Messier model) as valuable approximations for transcribing the observed results. The highest value of third-order susceptibility found for studied compounds was equal to <3> elec χ  = 3.0×10-20 m2/V2 (at the wavelength λω = 1064 nm, pulse duration 15 ps, average energy 1.6 mJ per pulse, pulse repetition frequency 10 Hz)..
