Title: <title>Multilens array for GEKKO XII glass laser system with circular aperture spherical element lens</title>
Abstract:A two-dimensional multi-lens array of 350 mm in diameter with 37 pieces of spherical element lenses is tested for improving the irradiation uniformity of the ICF target. Circular and hexagonal shapes ...A two-dimensional multi-lens array of 350 mm in diameter with 37 pieces of spherical element lenses is tested for improving the irradiation uniformity of the ICF target. Circular and hexagonal shapes of element lens aperture have been examined. The circular aperture is chosen for eliminating azimuthally asymmetric intensity distribution in the beam pattern. An approximate flat-top intensity distribution has been obtained at the focus of the principal lens. Beam patterns of coherent laser and partially coherent light (PCL) with the random phase plate (RPP) and the multi-lens array (MLA) have been measured at GEKKO XII glass laser system. The irradiation non uniformity of MLA on a spherical target is calculated from the measured beam patterns.Read More
