Formation mechanism of surface morphology in the process of CO2 pulsed laser processing of fused silica optics

Chao Tan et al.

Summary: Through numerical simulation and experimental research, the mechanism of surface morphology formation during CO2 pulsed laser processing of fused silica optics was comprehensively analyzed. It was found that the residual temperature between laser pulses was lower than the material's structural transition temperature, resulting in specific three-dimensional morphology features on the processed surface during laser scanning.

Combined studies of surface evolution and crack healing for the suppression of negative factors during CO2 laser repairing of fused silica

Chao Tan et al.

Summary: Research shows that material ablation and gasification recoil pressure are the main factors in forming specific crater shapes during the CO2 laser repairing process, while long-term low-power laser use can fully melt the material around the crack. Experimental studies have also proposed methods to suppress negative factors.
