Picosecond Laser Ablation of Millimeter-Wave Subwavelength Structures on Alumina and Sapphire
Qi Wen, Elena Fadeeva, Shaul Hanany +4
We use a 1030 nm laser with 7 ps pulse duration and average power up to 100 W to ablate pyramid-shape subwavelength structures (SWS) on alumina and sapphire. The SWS give an effect…
