Abstract
Intensity dependent transmission and laser-induced fluorescence were observed in liquid solutions of mesoionic compounds (MIC) pumped with nanosecond lasers operating at 1064, 604, and 570 nm. The results indicate that two-photon absorption (TPA) is the dominant mechanism which causes the observed behavior. The TPA cross-sections measured have values from 0.33×10−20 cm4/GW to 0.43×10−18 cm4/GW.
