Diffractive optical elements with a large diffraction angle require feature sizes down to sub-wavelength dimensions, which require a rigorous electromagnetic computational model for calculation. However, the computational optimization of these diffra

Diffractive optical elements (DOEs) which consist of microstructure surface relief permit the generation of the spatial distribution of light beams by using a single element. Due to their compact size, design flexibility, and mass productivity, they

The upscaling of laser micromachining processes with ultrashort pulses is limited due to heat accumulation and shielding effects. Multibeam scanning represents one of the strategies to overcome this drawback. It is in general realized by combining a

Recently, structured laser beams are gaining attention in laser–matter interactions and related applications of metamaterials and metasurfaces. Ablative laser printing using ultrashort, femto- or picosecond, structured laser pulses allows the large
