We report a new technique for producing high-efficiency XUV Bragg (volume) holographic optical elements by recording interference patterns in a photosensitive coating in either the visible or XUV region. Theoretical calculations and analysis of experimental results have successfully demonstrated the significance of this new fabrication methodology for XUV holographic optical elements, with over 25% diffraction efficiency achieved. In addition, volume holographic optics offer high flexibility in conventional and nonconventional operations, high laser-damage threshold and temperature stability, low surface roughness, and cost effectiveness in mass production.
