Dispersion of nonlinear refraction and two-photon absorption using a white-light continuum Z-scan.
We use a white-light continuum (WLC) Z-scan technique to measure the degenerate two-photon absorption spectrum and associated dispersion of the nonlinear refraction in ZnSe. The spectral components of the WLC source are separated by using a narrow band variable filter to minimize nondegenerate nonlinearities. We observe a change in sign of the ultrafast nonlinear refractive index around 0.7 of ...
متن کاملMeasurement of The Nonlinear Refractive Index by Z-scan Technique
In this seminar the third-order nonlinear optical phenomena are described. The emphasis is on the nonlinear refractive index n2. We describe the Z-scan technique, which is a simple method to determine n2. At the end we show how Z-scan method can be used to examine protein concentration in human blood.

متن کاملThiazole based novel functional colorants: Synthesis, characterization and nonlinear optical studies using picosecond Z-scan technique
Organic push–pull chromophoric system containing thiazole Schiff bases were synthesized from aminothiazole intermediate. These novel chromophores possessed excellent thermal and optical properties with complete transparency in the visible spectral region. Thermogravimetric analysis revealed that all dyes were thermally stable at temperatures above 300 C. The third-order nonlinear optical studie...
متن کاملModeling of Z-scan characteristics for one-dimensional nonlinear photonic bandgap materials.
We propose a Z-scan theory for one-dimensional nonlinear photonic bandgap materials. The Z-scan characteristics for this material are analyzed. Results show that the Z-scan curves for photonic bandgap materials with nonlinear refraction are similar to those of uniform materials exhibiting both nonlinear refraction and nonlinear absorption simultaneously. Effects of nonlinear absorption on refle...
