Abstract :
The third- and fifth-order optical nonlinearities from the titled molecule were investigated using Z-scan technique. The titled molecule exhibits two-photon absorption (2PA) and 2PA-generated excited-state absorption (ESA). A very interesting feature is that the titled molecule shows a high fifth-order nonlinearity, being about one-order of magnitude larger than the reported organic molecules. Due to this strong ESA, a highly efficient optical limiting effect was observed.
