Digital Engineering in Diffractive Optics for Precision Laser Processing

This article focuses on the application of digital engineering in diffractive optics for precision laser material processing. It examines methods for the development of diffractive optical elements (DOEs) and adaptive management approaches that enhance the accuracy and efficiency of laser processing. Key achievements are highlighted in numerical modeling, machine learning applications, and geometry optimization of optical systems, along with the integration of dynamic DOEs with laser systems for adaptive beam control. The discussion includes the development of complex diffractive structures with improved characteristics and new optimization approaches. Special attention is given to the application of DOEs in micro- and nanostructuring, additive manufacturing technologies, and their integration into high-performance laser systems. Additionally, challenges related to the thermal stability of materials and the complexity of adaptive DOE control are explored, as well as the role of artificial intelligence in enhancing laser processing efficiency.
