      abstract     = {Diamond is a highly suited material for radiation-resistant
                      X-ray optics, particularly for 4th-generation synchrotron
                      radiation sources with high brightness and X-ray
                      free-electron laser (XFEL) facilities operating at high
                      pulse energies. For various imaging applications, critical
                      factors such as spatial resolution, bandwidth flexibility,
                      and compact integration must be addressed in the design of
                      focusing optics. However, the manufacturing process by laser
                      ablation of diamond lenses often leads to residual
                      aberrations and limitations in achievable spot sizes, posing
                      challenges for high-resolution imaging applications. This
                      work introduces an innovative concept of
                      aberration-compensated X-ray lens cubes, composed of
                      bi-concave, two-dimensional diamond lens plates with a 25
                      µm radius of curvature, fabricated by femtosecond laser
                      ablation. A focal spot size of 52 nm × 51 nm was achieved
                      at 14 keV, with wavefront errors strongly reduced across a
                      wide photon energy range of 14 keV to 20 keV using multiple
                      corrective phase plates. These results demonstrate the
                      strong potential of our approach for nanoimaging
                      applications, advancing high-resolution X-ray focusing
                      capabilities for 4th-generation synchrotron radiation
                      facilities and XFELs.},
