| Popis: | Molecules with strong two-photon absorption have applications in photodynamic therapy and photonic devices. The effect of polarity of the medium and microemulsion on nonlinear optical properties of saffron is studied by the Z-scan technique with a CW laser at the 532 nm wavelength. The values of the nonlinear refractive index and two-photon absorption of saffron are found to increase with a decrease in the medium polarity and with an increase in the droplet size in the microemulsion. |
