3D intensity distribution of E′ focused by OAP with φ = 20.7° for R = 160 mm and θ_x = 0.016°. (a) Intensity profiles in cross-section. (b) Intensity profile in meridional plane. (c) Intensity profile in sagittal plane. Dashed lines present focus position in corresponding plane, and dashed–dotted line presents position of peak intensity. Intensity is indicated by color “heat”.
