Abstract

The concentration dependence of third order nonlinear optical susceptibility ( χ^<3> ) of copper phthalocyanine (CuPc) dissolved in tetrahydrofuran (THF) using the degenerate four wave mixing (DFWM) method at 532 nm was investigated. We present the linear dependence of the third order nonlinear optical susceptibility ( χ^<3> ) as a function of different concentration for CuPc dissolved in THF. We also calculated the second order hyperpolarizability ( γ) of CuPc solutions. Third harmonic generation (THG) measurements at the 1064 nm performed on CuPc thin films are also presented. We found that the χ^<3>_DFWM values are larger than the χ^<3>_THG ones. This variation observed in χ^<3>values, occurs probably due to the different resonance contributions in solution and solid state of CuPc. We show that in the case of DFWM measurements the one and two-photon resonant contributions at the Q and C-band increase χ^<3>_DFWM value of CuPc. In THG measurements, the three-photon resonance contribution at the Soret band gives rise to higher χ^<3>_THG value.
