Transition from saturable absorption to reverse saturable absorption of carmoisine dye under low-powered continuous wave laser excitation
Unique nonlinear optics (NLO) properties i.e. intensity-dependent nonlinear absorption and refraction of carmoisine (food dye) is studied using a single beam z-scan technique. A switchover behavior from a saturable absorption (SA) to reverse saturable absorption (RSA) is observed by increasing conce...
