The distance over which the charge state distribution evolves during the expansion of laser produced Sn plasma in vacuum is investigated experimentally. This distance is found to be less than 6 cm with a planar target irradiated by a 1.064 mum laser at 8.3x10{sup 11} W/cm{sup 2} but greater than 60 cm when a 10.6 mum laser at 2.5x10{sup 10} W/cm{sup 2} is used. The difference is attributed to the laser wavelength dependence of the coronal electron density and the subsequent recombination processes during expansion. Important implications to the extreme ultraviolet x-ray source application are discussed specifically.
