Measurement of the nonlinear refractive index of Cs D_1 line using z-scan

We present measurements of the nonlinear refraction coefficients for the D_1 line of cesium vapor. A variant of the z-scan technique is applied for which we scan the laser frequency across resonance for different sample positions and detect the transmission after an aperture in the far field. From ...
