First, theoretical considerations are recalled, in order to justify the choice of a probing infrared wavelength (CO2 laser at 10.6 mm). Since the considered plasma jet has a cylindrical symmetry, the deflection angle of the probing laser beam given by the gradient indexes allows to determine the electron density on the axis of the plasma column. %8 2001-09-01
