Abstract:
The work is devoted to the analysis of systematic technological errors arising during the production of diamond DOEs by way of direct laser ablation. The aim of this article is a numerical analysis (within the framework of the electromagnetic theory of diffraction gratings) of the influence of errors in the formed relief at the junctions of elementary structuring areas. The paper draws conclusions on the nature of the influence of technological errors on the operation of DOEs and formulates recommendations for minimizing energy losses associated with the presence of errors.

Keywords:
diamond DOE, local technological error, laser ablation, diffraction grating, electromagnetic theory.
