Measurement of the nonlinear refractive index of air constituents at mid-infrared wavelengths.
We measure the nonlinear refractive index coefficients in N₂, O₂, and Ar from visible through mid-infrared wavelengths (λ=0.4-2.4 μm). The wavelengths investigated correspond to transparency windows in the atmosphere. Good agreement is found with theoretical models of χ((3)). Our results are essential for accurately simulating the propagation of ultrashort mid-infrared pulses in the atmosphere.
متن کاملMeasurement of the thermal contribution to the nonlinear refractive index of air at 1064nm.
The thermal contribution to the nonlinear refractive index of air at 1.064mum was measured with a high-finesse Fabry-Perot cavity and a 500-mW cw laser beam. At room temperature and pressure, the nonlinear refractive-index coefficient of air was found to be n(2)((th))=(-1.9+/-0.2)x10 (-14) cm(2)/W for a beam waist radius of 0.23 mm and was found to be independent of the relative humidity. The t...
متن کاملRefractive Index of Humid Air in the Infrared: Model Fits
The theory of summation of electromagnetic line transitions is used to tabulate the Taylor expansion of the refractive index of humid air over the basic independent parameters (temperature, pressure, humidity, wavelength) in five separate infrared regions from the H to the Q band at a fixed percentage of Carbon Dioxide. These are least-squares fits to raw, highly resolved spectra for a set of t...
متن کاملMeasurement 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...
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.
