| Abstract | ||
| Nonlinear optical properties of acid red 92 doped PMMA film have been investigated. The measurements were performed using CW laser at 532 nm wavelength by employing Z-scan technique. The nonlinear refractive index is found to be of the order of 10−9 cm2/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 acid red 92 doped PMMA film was also investigated. The sample with 12 mM concentration has the best limiting effect among the other two concentrations. | ||
