Researchers achieve fused silica with high damage threshold by combing chemical etching and laser polishing
Some researchers have achieved fused silica that can take a high amount of damage. According to Phys.org: “Laser damage in fused silica, particularly ultraviolet laser damage, is still a key problem limiting the development of high-power laser systems. The traditional processing method of fused silica goes through the processes of grinding and chemical mechanical polishing
