Abstract:
The article considers the production and research of a four-level diffractive optical element (DOE) focusing a Gaussian beam into a circle. Direct laser recording on a photoresist was used as the production technology. The value of the measured energy efficiency of the element is in good agreement with the theoretical estimate and amounts to approximately 80%.

Keywords:
four-level DOE, diffractive optical element, Gaussian beam, laser recording on a photoresist.
