Solid-state dye-doped polymers are attractive alternative to the conventional liquid dye solutions. In this paper, nonlinear properties of the dye Acid Fuchsin has been studied. The third-order nonlinear optical properties of Acid Fuchsin dye in 1-butanol and dye-doped polymer film were measured by the Z-scan technique using 532 nm diode pumped Nd:Yag laser. This material exhibits negative optical nonlinearity. The dye at 0.4 mM concentration exhibited nonlinear refractive coefficient (n2 = −8.72 × 10−8 and −10.308 × 10 −8 (cm2/W) in liquid and solid media, respectively), nonlinear absorption coefficient (β = −7.69 × 10−4 and −8.294 × 10−4 cm/W in liquid and solid media, respectively) and susceptibility (χ(3) = 4.33 × 10−6 and 5.13 × 10−5 esu in liquid and solid media, respectively). These results show that Acid Fuchsin dye has potential applications in nonlinear optics.
