CO(2) laser is an interesting tool to repair defects on silica optics. We studied UV nanosecond laser-induced damage in fused after heating. The localization of sites and the threshold are closely related stress area induced by By applying a suitable second heating, we managed eliminate debris issued from redeposited modify area. As consequence, significant increase resistance has been observed. This process offers possibility improve repairing sufficiently extend lifetime components.
