abstract = "The concentration dependence of third order nonlinear optical susceptibility (chi(<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 (chi(<3 >)) as a function of different concentration for CuPc dissolved in THE We also calculated the second order hyperpolarizability (gamma) of CuPc solutions. Third harmonic generation (THG) measurements at the 1064 nm performed on CuPc thin films are also presented. We found that the chi(<3 >)(DFWM) values are larger than the chi(<3 >)(THG) ones. This variation observed in chi(<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 chi(<3 >)(DFWM) value of DFWM CuPc. In THG measurements, the three-photon resonance contribution at the Soret band gives rise to higher chi(<3 >)(THG) value.",
