The traditional processing method of fused silica goes through the processes of grinding and chemical mechanical polishing (CMP). This method is time-consuming to achieve an ultra-smooth surface, and is easy to cause surface and sub-surface defects, resulting in a significant reduction in the surface damage threshold of the fused silica.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-11-fused-silica-high-threshold-chemical.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Researchers achieve fused silica with high damage threshold by combing chemical etching and laser polishing<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Laser damage in fused silica, particularly ultraviolet laser damage, is still a key problem limiting the development of high-power laser systems.
