Surface flaws on high power laser optics can be effectively removed using Rapid Ablation Mitigation (RAM) methods. RAM consists of raster‐scanning pulsed, high intensity (∼MW/cm 2 ) far‐infrared laser light across damaged material to create precisely shaped cones as shown. Micro‐scale morphology, residual stress, and re‐deposition are controlled by optimizing pulse length (∼10 μs), repetition rate (0.5‐2kHz) and laser power. Further details can be found in the article by Manyalibo J. Matthews and co‐worker on page 247 .
