Abstract
A metalenslet beam homogenizer offers an alternative to classical beam homogenization techniques by leveraging flat optical metasurfaces. The metalenslet beam homogenizer would be beneficial, for example, for high power laser applications, such as laser material processing, digital projection, optical lithography, and additive manufacturing in which it is necessary to expose a certain area on a workpiece to a well-defined amount of optical radiation. The metalenslet beam homogenizer provides benefits by enhancing the beam homogenization quality, reducing size and complexity, and lowering optical power loss. It does so by using nanophotonic metasurface lenses and offers higher homogenization quality by mitigating the impact of diffraction and reducing the size of the optical system by combining the functionality of multiple optical elements into fewer devices. Overall, the metalenslet beam homogenizer represents a significant improvement over conventional beam homogenizers, offering a more efficient, more compact, and more reliable way to produce high-quality beam uniformity.
