Measurement of high order Kerr refractive index of major air components (vol 17, pg 13429, 2009)

A clarification is missing concerning the high order Kerr nonlinearities deduced from our experimental data published in [Opt. Express 17, 13429-13434 (2009)]. Here, we rectify this omission by making explicit the distinction between cross-Kerr and Kerr effects, and by extrapolating the value of the nonlinear refractive index for the last effect. Since the occurrence of sign inversion in the Kerr effect is not affected, the overall report in [Opt. Express 17, 13429-13434] remains valid. (C) 2010 Optical Society of America
