Measurement 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.

nonlinear refractive index measurement in semiconductor-doped glasses

there are several techniques in use for non-linear refractive index measurement, namely, interferometric techniques, in which conventional inter-ferometers are used, degenerate for wave mixing (dfwm), and z-scan, each of these techniques suffers from some shortcmings. for example conventional interferometers like fabry-perot and twyman-green need high quality optical components, unwanted reflec...

Gas analysis by refractive index measurement.

A B C light in a medium is difficult, it is quite easy to compare the velocity of light in one medium with the velocity of light in another. A suitable instrument for this purpose is the Rayleigh Interference Refractometer. This instrument is shown diagramatically in figures 1 and 2. Figure 1 is a plan view showing the components as they appear from above. Figure 2 is a side view of the same ar...

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 ...

Measurement of the dispersion of air and of refractive index anomalies by wavelength-dependent nonlinear interferometry.

We carry out wavelength-dependent second harmonic interference experiments using thin films of an organic dye as nonlinear optical sources. While the measured difference of refractive index between the fundamental and second harmonic wavelengths follows the theoretical expectation for air in a wide spectral region, anomalous dispersion is observed when the second harmonic light lies in the abso...
