Abstract
The third-order nonlinear optical properties of the octa-octyloxy phthalocyanine free base were studied by Z-scan using 35-ps laser pulses at 532 nm in toluene. The nonlinear refractive index or the refractive cross section, and the excited singlet state absorption cross section were determined. The optical limiting performances at both nanosecond and picosecond time scales have been investigated. The results suggest that the octa-octyloxy phthalocyanine free base is promising for optical limiting materials.
