An experimental investigation about laser beam homogenization using gas jets is presented in this paper. The results, obtained at PALS iodine laser facility using the 3 omega wavelength and irradiances of about 10(15) W/cm(2), showed that the use of high pressure gas jets (up to 10 bar of Argon) can be effective in reducing strong laser beam non-uniformities artificially introduced by inserting a wedge arrangement on half of the beam.

Abstract
An experimental investigation about laser beam homogenization using gas jets is presented in this paper. The results, obtained at PALS iodine laser facility using the 3 omega wavelength and irradiances of about 10(15) W/cm(2), showed that the use of high pressure gas jets (up to 10 bar of Argon) can be effective in reducing strong laser beam non-uniformities artificially introduced by inserting a wedge arrangement on half of the beam.
