Limits to the determination of the nonlinear refractive index by the Z-scan method
We analyze the limitations imposed by sample absorption on the determination of the nonlinear refractive index by the Z-scan technique. By using a nanostructured thin film consisting of Cu nanocrystals embedded in a dielectric Al2O3 matrix as an example, we show that thermo-optical effects appearing when linear absorption is significant can be strongly misleading in the interpretation of the re...
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.

Measurement of the Nonlinear Refractive Index of LiNb03 by Z-scan Technique
Nonlinear refractive index, n of an undoped z-cut photorefractive LiNbO3 crystal has been investigated here by the Z-scan technique using a continuous wave (cw) laser beam from a multiline argon-ion laser. Here both the sign and magnitude of the measured n are considerably different from the reported z-scan result in LiNbO3 obtained with picoseconds pulsed laser at 532 nm but in good agreement ...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
