摘要：

Nonlinear optical properties of Phloxine B dye doped PMMA films have been investigated. The measurements were performed using CW laser at 532 rim wavelength by employing Z-scan technique. The nonlinear refractive index is found to be of the order of 10(-9) cm(2)/W. Moreover, a variation of nonlinear refractive index with doping concentration is observed. Significant optical multiple diffraction rings of the sample under CW illumination at 4 mM, 8 mM and 12 mM doping concentrations were observed. The optical power limiting behavior of Phloxine B dye doped PMMA films were also investigated. The sample with 12 mM concentration has the best limiting effect among the other two concentrations.
