In this research effort, the nonlinear refraction (NLR) and nonlinear absorption (NLA) of Acid Fuchsin dye solution were measured using Z-scan technique. Both properties were measured through the application of open aperture and closed aperture Z-Scan measurements in order to analyse the relationship between different laser input fluences and on four different dye concentrations (0.03 mM, 0.05 mM, 0.10 mM, and 0.20 mM). The results showed that both; NLR, NLA and optical limiting properties were observed starting from 0.05 mM. There is a reduction in terms of its NLR value observed as the concentrations increased with 0.03 mM has the highest value of n2. It is shown that the increment of NLA value is also observed as the concentrations increased. The low optical limiting (OL) threshold is observed around 0.04 W under continuous wave (CW) 532 nm laser beam. This shows that acid fuchsin dye has the capability as an optical limiter in photonics applications.

在这项研究工作中，使用Z扫描技术测量了酸性品红染料溶液的非线性折射（NLR）和非线性吸收（NLA）。通过应用开孔和闭孔Z扫描测量来测量这两种性能，以分析不同激光输入通量和四种不同染料浓度（0.03 mM，0.05 mM，0.10 mM和0.20 mM）之间的关系。结果表明：从0.05 mM开始观察到NLR，NLA和光学极限特性。随着浓度的增加（0.03 mM的值具有最高的n2），其NLR值有所降低。结果表明，随着浓度的增加，NLA值也会增加。低光学极限（OL）阈值在0附近观察到。在连续波（CW）532 nm激光束下为04W。这表明酸性品红染料具有在光子学应用中作为光学限制剂的能力。
