Abstract
We present a method for producing durable thin optics for high-power lasers, using scalable process for spatially patterned glass engraved metasurface. The process is based on forming an etch-mask using laser raster-scan of a thin metal film on a glass, followed by dry-etching and removal of the metal mask. We present fabricated structures, and characterization of their optical performance, mechanical stability, and laser damage performance.
