Nonlinear optical properties of Coumarin-based compounds i.e., 3-acetyl-7-diethylaminocoumarin (C3) and 7Ethylamino-4-trifluoromethylcoumarin (C500) is reported by Z-scan technique (Nd: YAG Continuous-wave 532 nm). The conventional C500 compound exhibited NLR properties in the order of n2 = 10-9, whereas the synthesized C3 compound manifested both NLR and NLA properties around n2 = 10-9 and beta = 10-4, respectively. The results are obtained from different laser power PC500 = 0.10-0.18 W, while PC3 = 0.20-0.28 W. Both compounds provided excellent NLO attributes at consistent and stable outputs of open and closed-aperture signals, resulted in eminence of NLR and NLA values. The C3 compound is manifested reverse saturable absorption, optical limiting properties, and threshold at 0.3814 W. The exclusivity of NLR in C500 makes it suitable to develop as an optical switcher while synthesized C3 compound is more suitable as an optical limiter for safety.
