The effectiveness of multi-wedge plates array for the improvement of the laser irradiation uniformity on the pellet target in inertial confinement fusion has been investigated. A multi-wedge plates array of 90-mm in diameter was fabricated with wedge plates of 7 pairs, which ad a size of 30-mm diameter and a wedge angle of about 0.1 degrees. Also, to prevent the diffraction caused by each wedge plates, a soft aperture with the transmission profile of 16th super gaussian was designed and fabricated. As the result, it was confirmed that the array decreased the low- mode uniformity and is able to control the beam profile.
