The results of recent studies on the optical limiting properties of BODIPY dyes at 532 and 1064 nm are described and compared. The optical limiting properties of novel 1,7-dimethyl-3,5-di-4-dihydroxyborylstyryl- and 3,5,7-tristyryl-1-methyl-BODIPY dyes were studied in CH2Cl2 and C6H6 and polystyrene thin films using the open aperture Z-scan technique at 532 nm with nanosecond laser pulses to provide an example of how the effective nonlinear absorption coefficient, the third order susceptibility, hyperpolarizability and limiting thresholds can be calculated.

AbstractThe first experimental investigation of an optical limiting device based on a suspension of spherical particles in a surrounding liquid is presented. The expected property is the non-linear light scattering based on a refractive index mismatch between the two components that appears at high intensity. Several experiments performed at 532 nm with nanosecond laser pulses provide good indication that such non-linear scattering is observed.

Optical limiting (OL) performances of ZnS nanotube and ZnS nanoparticle in N, N dimethyllformaide (DMF) were comparatively investigated by using nanosecond laser pulses at 532 nm. Experimental results indicate that the shapes of ZnS nanomaterials have effect on their OL performances, and ZnS nanotube exhibits stronger OL performance than ZnS nanoparticle. The results were analyzed by use of the Maxwell-Garnett Effective Medium theory (MGT).

The third-order nonlinearities of PbS nano-dot and nano-belts have been investigated using the Z-Scan technique with nanosecond laser pulses at 532nm. The effect of the PbS semiconductor nanometer-size and spatial forms on the third-order optical nonlinearities and optical limiting properties would be discussed when the nanometer-size were larger than the exciton size. The optical limiting mechanism of materials was discussed in the nanosecond time domain.
