  We report on performance of chemical vapor deposited (CVD) single crystal
diamond plates as side bounce monochromators for high photon energies
($\gtrsim$~20 keV) in the Laue geometry. Several crystals were tested
in-operando high-heat-load conditions at A1 undulator station of Cornell High
Energy Synchrotron Source. Up to 10$\times$ enhancement in the reflected x-ray
flux was observed compared to that delivered by IIa diamond plates grown by
high-pressure high-temperature method. Wavefront distortions were measured
using analyzer-based x-ray diffraction imaging. Focusing of a portion of the
reflected beam was demonstrated using Pt-coated mono capillary optics at a
photon energy of 46 keV.
