Abstract:The present work reports on the ultrafast nonlinear optical (NLO) properties of a series of D−π−Α and D−A push− pull carbazole-based dyes and establishes a correlation between these properties and their efficiency for potential photonic and optoelectronic applications such as multiphoton lithography (MPL). The ultrafast NLO properties of the studied dyes are determined by two distinct experimental techniques, Z-scan and pump−probe optical Kerr effect (OKE), employing 246 fs laser pulses at 515 nm. The results … Show more
