Abstract
Recent degenerate-four-wave-mixing (DFWM) studies, performed on Bis(phthalocyanines)1 at 1064 nm have shown that these materials possess large optical nonlinearities. In this paper the real and imaginary parts of the third-order susceptibility are investigated by using the Z-scan technique and nonlinear-absorption measurements. The results are compared with DFWM measurements.
