The nonlinear absorption coefficient has been measured through the open aperture Z-scan technique, whose values increased exponentially from 0.997×10<sup>-3</sup> to 11.7×10<sup>-3</sup> cm/W as the dye concentration increased from 3.7×10<sup>-5</sup> to 74.6×10<sup>-5</sup> M. Also, DB1 optical power limiting characteristics appeared at high laser light intensities, whereby very dilute solution of the order of ~10<sup>-4</sup> M was sufficient to limit the transmitted ‎power of the incident laser light by ~90%.
