Basic properties of the fourth harmonic conversion of 1.053-..mu..m laser radiation with KDP crystals are experimentally determined. Optimization of crystal thickness, based on numerical simulations is discussed. A large aperture conversion cell combining second and fourth harmonic generators has been designed. Overall conversion efficiencies (..omega.. ..-->.. 4..omega..) in excess of 40% have been achieved for incident laser intensities between 1 and 2.5 GW/cm/sup 2/.
