Paper Abstract

The optical limiting behavior of trans-diphenyl-1,3-butadiene (DPB), 2,2'-3- methyldithienylethylene (MDTE), 2,2'-dithienyl-1,3-butadiene (DTB) and trans- 2,2'-dibenzthienylethylene (DBTE) in chloroform was studied. Solutions of these compounds are nonresonant at 532 nm. The effects of laser beam spot size at 532 nm on the onset of limiting and the temporal profiles of the transmitted laser pulses were examined. The results indicate two photon absorption as the major contributor to the optical limiting. Two photon absorption cross sections were estimated from the optical limiting data.
